The Best Trailer Hitches for Trucks and SUVs: 5 Picks Compared
Five real trailer hitches compared for trucks and SUVs, from a cheap fixed ball mount to adjustable dual-ball heads and a weight distribution kit.
Most trucks and SUVs already have a square receiver under the bumper. The part you actually shop for is the hitch that slides into it, and that choice decides whether your trailer rides level, hooks up in one try and stays calm at highway speed. This guide compares five real options sold on Amazon: the B&W Tow & Stow adjustable dual-ball mount, the plain CURT 45056 loaded ball mount for light trailers, the slim steel Andersen EZ Hitch with a deep 8 in drop for lifted trucks, the Weigh Safe mount with a tongue weight gauge built into the shank, and the CURT 17062 weight distribution hitch with sway control for heavy travel trailers. We compared them on ball sizes, drop and rise, published weight ratings, material and what owners report over time. By the end you will know which format matches your trailer, how much hitch your load really needs, and where paying more buys real capability instead of shine.

Best Overall
B&W Trailer Hitches Tow & Stow Adjustable Ball Mount TS10037B
by B&W Trailer Hitches
One solid steel ball mount that carries both common ball sizes, adjusts for trailer height and tucks under the bumper when you are done towing.
What we like
- Two ball sizes on one head, so a small utility trailer and a big boat trailer both hook up without swapping parts
- The head pivots and locks in several positions, so you can level the trailer instead of towing it nose down
- Folds up under the bumper when nothing is hooked to it, which keeps shins safe and looks tidy
- Made from solid steel in the United States with a strong owner reputation for holding up over many seasons
What we don't
- At about 25 lb it is a two-hand job to lift in and out of the receiver, heavier than the Andersen and Weigh Safe picks
- The 2 in shank version is capped at 10,000 lb, so heavier fifth wheel or gooseneck loads need a different tool
- Costs several times what a plain fixed ball mount costs, which is hard to justify if you only tow one trailer
| Hitch type | Adjustable dual-ball mount that folds under the bumper |
|---|---|
| Receiver fit | 2 in receiver |
| Max trailer weight | 10,000 lb GTW |
| Drop rise | 5 in drop, flips over for rise |
| Ball sizes | 2 in and 2-5/16 in |
| Install difficulty | Easy |
| Price bracket | $$ |
The Tow & Stow wins Best Overall because it solves the two problems that send people back to the parts store. It carries a 2 in ball and a 2-5/16 in ball on the same head, and the head adjusts up and down so you can pull the trailer level. Most owners buy a second ball mount within a year or two. This one is meant to be the last one you buy.
The fold-away trick is the part people notice day to day. When you unhook the trailer, the whole head swings up and out of the way instead of sitting there waiting to catch your leg. That sounds small until you have parked in a tight garage or backed up to a loading dock.
Build quality is the other reason it ranks first. It is solid steel, made in the United States, and owner reviews consistently report years of use without slop in the head or rust bleeding through the coating. Cheap adjustable hitches often loosen at the pivot after a season of rough roads, which is exactly where this design is strongest.
The honest limitation is weight and price. This is a heavy chunk of steel, so pulling it out of the receiver and carrying it to the tailgate is real work compared with the slimmer Andersen EZ Hitch. The 2 in shank version also stops at 10,000 lb, and the price sits near premium territory for something that is still just a ball mount.
Buy it if you tow more than one trailer, or if your trailer sits at a different height than your truck’s receiver. Skip it if you own one light trailer and never change setups, where the CURT 45056 covers you for far less. If your trailer is a big travel trailer that wanders in crosswinds, the CURT 17062 weight distribution hitch is the safer answer no matter how good the ball mount is.
Research-based pick: this recommendation is based on product data, owner feedback and comparison with products we have tested, not on direct hands-on testing.
Buy it if: Truck and SUV owners who pull more than one trailer and want one hitch that covers both ball sizes and several heights.
Skip it if: You tow a single light trailer at one fixed height, where the CURT 45056 does the same job for a fraction of the money.
Best Budget
CURT 45056 Loaded Ball Mount with 2 Inch Ball and 4 Inch Drop
by CURT
A plain steel ball mount that arrives with the ball already torqued on, which is all most people towing one light trailer actually need.
What we like
- Ships with the 2 in ball installed and torqued at the factory, so there is no wrench work before your first tow
- Rated 7,500 lb, which covers most utility trailers, small boats, jet skis and single-axle campers
- Hitch pin and clip are in the box, so it works the minute it comes out of the packaging
- Thousands of owner reviews with a steady high rating, which is rare reassurance at this price
What we don't
- Fixed 4 in drop only, so if your trailer sits higher or lower you have to buy a different mount
- One ball size, so a trailer with a 2-5/16 in coupler will not connect to it at all
- The hollow shank rattles in the receiver unless you add a pin lock or an anti-rattle wedge
| Hitch type | Fixed ball mount with the ball already torqued on |
|---|---|
| Receiver fit | 2 in receiver, hollow 2 in shank |
| Max trailer weight | 7,500 lb GTW |
| Drop rise | 4 in drop |
| Ball sizes | 2 in |
| Install difficulty | Easy |
| Price bracket | $ |
The CURT 45056 is the Best Budget pick because it does the one thing a ball mount has to do and nothing else. It slides into a 2 in receiver, it holds a 2 in ball, and it drops the ball 4 in below the receiver so a typical trailer rides level behind a typical truck.
What sets it apart from the no-name mounts near the same price is that CURT torques the ball at the factory. A loose trailer ball is one of the more common causes of a trailer coming off on the highway, and buying a ball mount and ball separately puts that torque job on you. Here it is already done, and CURT is an established towing brand rather than a marketplace label that appears and disappears.
The problem it solves is simple money. Adjustable hitches cost several times more, and if your trailer height never changes you get nothing back for that spend. For a homeowner with one utility trailer, this is the right amount of hitch.
The real limitation is that it is locked in. One drop height, one ball size. Borrow a friend’s boat trailer with a 2-5/16 in coupler and you are stuck in the driveway. It is also a hollow shank, so expect some rattle in the receiver unless you add a locking pin or an anti-rattle device.
Buy it if you know your trailer and that is not going to change. Choose the B&W Tow & Stow instead if you tow several trailers, or the Andersen EZ Hitch if your truck sits high and 4 in of drop is nowhere near enough.
Research-based pick: this recommendation is based on product data, owner feedback and comparison with products we have tested, not on direct hands-on testing.
Buy it if: Anyone towing one light trailer at a known height who wants a dependable ball mount without spending real money.
Skip it if: You tow trailers of different heights or coupler sizes, where the B&W Tow & Stow or Andersen EZ Hitch pay for themselves.
Best for Lifted Trucks
Andersen Hitches EZ Hitch 8 Inch Drop or Rise Adjustable Ball Mount
by Andersen Hitches
A slim steel ball mount with a deep 8 in drop or rise, built for trucks whose receivers sit far above the trailer coupler.
What we like
- 8 in of drop covers lifted trucks and tall stock pickups that a standard 4 in mount cannot level
- Flips over for 8 in of rise, so the same part works behind a low car hauler or a lowered vehicle
- At 20.6 lb it is lighter and slimmer than the B&W head, so it is easier to lift and easier to store under a seat
- Two-sided combo ball gives you 2 in and 2-5/16 in couplers without carrying a second mount
What we don't
- The combo ball has to be flipped and re-secured to change sizes, which is slower than the B&W head that carries both balls at once
- Andersen does not list a tongue weight rating in this listing, so heavy tongue loads need a check with the maker first
- The polished steel finish is not powder coated, so it needs wiping down and a little grease to stay rust free
| Hitch type | Adjustable ball mount with a two-sided combo ball |
|---|---|
| Receiver fit | 2 in receiver |
| Max trailer weight | 10,000 lb with the 2 in ball, 14,000 lb with the 2-5/16 in ball |
| Drop rise | 8 in drop or 8 in rise |
| Ball sizes | 2 in and 2-5/16 in combo ball |
| Install difficulty | Easy |
| Price bracket | $$ |
Lift a truck and towing gets harder in a way nobody warns you about. The receiver rises with the frame, the trailer coupler does not, and suddenly the trailer rides nose high. That puts weight on the back axle of the trailer, hurts braking and makes sway more likely. The Andersen EZ Hitch wins Best for Lifted Trucks because it puts the ball a full 8 in lower than the receiver, which is enough for most lifted half tons and plenty of stock three quarter tons.
What makes it different from the other deep drop mounts is how slim it is. Most of them are heavy, awkward things. This one is all steel, certified to SAE J684, and still comes in at 20.6 lb, so you can carry it in one hand and it stores flat instead of eating half a truck box. Andersen also rates it 10,000 lb with the 2 in ball and 14,000 lb with the 2-5/16 in ball, which is more capacity than the budget CURT mount by a wide margin.
The compromise is the combo ball. Both sizes live on one shaft, so switching coupler sizes means loosening the ball, flipping it and putting it back correctly. That is a minute of work in a parking lot, and it is slower than the B&W Tow & Stow, which simply spins to present the other ball.
The other honest gap is that the listing does not publish a tongue weight rating. If your trailer has a heavy tongue, confirm the number with Andersen before you load it. The polished finish also wants an occasional wipe and a little grease, since it is not powder coated like the CURT and B&W picks.
Buy it if your truck sits high and you want a slim mount that fixes trailer angle. Choose the B&W Tow & Stow if you swap ball sizes constantly, or the CURT 17062 if the trailer behind you is a big travel trailer that needs weight moved forward.
Research-based pick: this recommendation is based on product data, owner feedback and comparison with products we have tested, not on direct hands-on testing.
Buy it if: Owners of lifted or tall trucks who need a big drop to pull a trailer level, and who do not want to wrestle a bulky mount in and out of the receiver.
Skip it if: Your truck is stock height and your trailer already tows level, since you are paying for drop you will never use.
Best for Checking Tongue Weight
Weigh Safe Aluminum Adjustable Ball Mount with Tongue Weight Scale, 6 Inch Drop
by Weigh Safe
An adjustable aluminum ball mount with a weight gauge built into the shank, so you can see your tongue weight every time you hook up instead of guessing.
What we like
- The built-in gauge reads tongue weight as you lower the trailer onto the ball, which is the number most towing problems trace back to
- Adjusts through 6 in of drop and flips for rise, so it levels the trailer as well as any adjustable mount here
- Stainless steel balls in both common sizes resist rust better than plated steel balls
- Keyed alike lock set secures the ball mount and the receiver pin with one key
What we don't
- The gauge is a rough field check, not a certified scale, so a loaded trailer near its limit still deserves a proper weigh station run
- Weigh Safe does not list a tongue weight rating in this listing, so heavy tongues need confirming with the maker
- The most expensive ball mount here by a clear margin, and the gauge is the only thing you get for that money
| Hitch type | Adjustable ball mount with a built-in tongue weight scale |
|---|---|
| Receiver fit | 2 in receiver |
| Max trailer weight | 12,500 lb GTW |
| Drop rise | 6 in drop, flips over for rise |
| Ball sizes | 2 in and 2-5/16 in stainless steel |
| Install difficulty | Easy |
| Price bracket | $$$ |
Tongue weight is the number that decides whether a trailer tracks straight or starts swinging. Too little and the trailer sways. Too much and the truck’s rear squats and the steering goes light. Most people never measure it. The Weigh Safe wins Best for Checking Tongue Weight because the measuring tool is built into the hitch you already have to use.
The gauge sits in the shank. As you crank the trailer down onto the ball, the load presses on the gauge and a dial shows the tongue weight in pounds. If the reading is far off the usual 10 to 15 percent of trailer weight, you move cargo forward or back and watch the number change. That feedback loop is worth more than any sway bar for anyone who loads a trailer differently each trip.
Everything else about it is a good adjustable mount. Aluminum body, 6 in of drop that flips for rise, and stainless steel balls in 2 in and 2-5/16 in. It levels the trailer the same way the B&W and Andersen picks do.
The honest limits are two. The gauge is a hydraulic field check, not a certified scale, so treat it as a guide rather than proof for anything near a legal limit. And the price is the highest of the ball mounts in this guide, which is a lot to pay if your trailer is always loaded the same way.
Buy it if you haul different loads and want a fast reality check at the hitch. If you already know your tongue weight is fine, the B&W Tow & Stow gives you the same adjustability and dual balls for less. If tongue weight is high because the trailer is a large travel trailer, you need the CURT 17062 to move that weight forward, not just measure it.
Research-based pick: this recommendation is based on product data, owner feedback and comparison with products we have tested, not on direct hands-on testing.
Buy it if: Owners who load their own trailer and want to know whether the tongue is too light or too heavy before pulling onto the road.
Skip it if: You tow the same trailer loaded the same way every time and already know its tongue weight is right.
Best for Heavy Travel Trailers
CURT 17062 Round Bar Weight Distribution Hitch with Sway Control
by CURT
A complete weight distribution kit with built-in sway control that levels the truck and calms a big trailer, for loads a plain ball mount cannot handle safely.
What we like
- Spring bars push tongue weight back onto the front axle, so the headlights stop pointing at the trees and the steering stays normal
- Friction sway control is part of the kit, which is the single biggest help in crosswinds and truck passes
- Ships with the 2-5/16 in ball already torqued to the head, so there is no separate ball purchase
- Grease zerk in the head keeps the bar sockets quiet instead of squeaking at every turn
What we don't
- Setup takes measuring, trial and error and a torque wrench, and a wrong setup is worse than no weight distribution at all
- Hooking up takes longer every single trip than dropping a ball mount in the receiver
- Only fits trailers with A-frame tongues and enough clearance for the bar brackets, so many utility and boat trailers cannot use it
| Hitch type | Round bar weight distribution hitch with sway control |
|---|---|
| Receiver fit | 2 in shank for a 2 in receiver |
| Max trailer weight | 10,000 lb GTW |
| Drop rise | Adjustable head height instead of a fixed drop |
| Ball sizes | 2-5/16 in, torqued at the factory |
| Install difficulty | Moderate |
| Price bracket | $$$ |
At some point a trailer stops being a ball mount problem. When the tongue weight is high enough to squat the truck, no amount of adjusting a ball height fixes it, because the weight itself is in the wrong place. The CURT 17062 wins Best for Heavy Travel Trailers because it moves that weight instead of just holding it.
Here is what it does. Two forged spring bars run from the hitch head back to brackets on the trailer tongue. Tightening them levers weight off the truck’s rear axle and spreads it to the front axle and the trailer axles. The truck sits level, the headlights aim at the road, and the steering keeps its normal weight. Built into the same kit is a friction sway control bar, which fights the side to side wag that big box trailers pick up when a semi goes by.
It is rated to 10,000 lb trailer weight with 800 to 1,000 lb of tongue weight, and the 2-5/16 in ball comes torqued to the head, so you are not shopping for parts to finish the job.
The real cost is effort. Weight distribution setup means measuring your truck’s fender heights before and after, adjusting head tilt, picking the right chain link on the bars and checking your work. Get it wrong and you can make handling worse than stock. Every hookup afterward is also slower than a ball mount, and the system needs an A-frame tongue with room for the brackets, which rules out most utility and boat trailers.
Buy it if your trailer is large enough to change how the truck sits. If your trailer is light and simply rides at the wrong angle, the B&W Tow & Stow or the Andersen EZ Hitch solve that far more simply.
Research-based pick: this recommendation is based on product data, owner feedback and comparison with products we have tested, not on direct hands-on testing.
Buy it if: Anyone pulling a travel trailer near 5,000 lb or more where the truck squats and the trailer feels nervous at highway speed.
Skip it if: Your trailer is light, has no A-frame tongue, or already tows level, where a simple ball mount is the better tool.
How we chose#
This is a research-based guide, not a hands-on towing test. We started with the hitch brands that tow shops and trailer owners name most often, then checked every pick against its live Amazon listing: the receiver size, the published trailer weight and tongue weight ratings, drop and rise, ball sizes and material. Where a maker does not publish a number, we say so rather than filling the gap with a guess.
We deliberately spread the picks across formats instead of ranking five near-identical ball mounts. That means one cheap fixed mount, two adjustable dual-ball mounts at different price points, one adjustable mount with a tongue weight gauge, and one full weight distribution kit. Listings with thin review histories, unclear ratings or no established brand behind them were passed over, because a hitch is a part where failure means a loose trailer.
What to consider before buying#
Start with your trailer, not your truck. The coupler decides the ball size, the trailer’s loaded weight decides the rating you need, and the height difference between coupler and receiver decides the drop. Those three numbers rule out most of the market in about five minutes.
Then be honest about how many trailers you tow. One trailer at one height means a fixed mount is all you need. Two or three different trailers means an adjustable dual-ball head saves you from a drawer full of mismatched mounts, and saves the trip home when the ball is the wrong size.
Last, check what the truck does when you hook up. If the rear drops and the front lifts, that is the signal to move up to weight distribution rather than shopping for a better ball mount.
Ball size, drop and getting the trailer level#
A level trailer is not a cosmetic thing. When the nose points up, weight shifts to the rear trailer axle, braking gets worse and sway starts at lower speeds. When the nose points down, the tongue pushes on the truck and the steering goes light.
Measure with the trailer sitting level on flat ground. Ground to the bottom of the coupler, ground to the top of the receiver opening, subtract, and that is your drop. Then confirm the ball size stamped on the coupler. The CURT 45056 covers the common 4 in drop with a 2 in ball. The B&W Tow & Stow and Andersen EZ Hitch carry both ball sizes and adjust through several heights, which is what you want if the trailers in your life keep changing. The same receiver also has to work for other gear, and if you carry bikes on the back of the truck, our guide to the best hitch bike racks covers what fits alongside a towing setup.
When you need weight distribution instead#
There is a line where a ball mount stops being enough. It usually shows up around 5,000 lb of trailer, or any time tongue weight is more than about 10 percent of what the truck can handle without squatting. Signs are easy to read: the rear bumper drops, headlights point up, steering feels vague, and the trailer wags when a semi passes.
That is the job of the CURT 17062. Spring bars transfer tongue weight forward, and the friction sway bar resists side to side movement. The trade is setup time and complexity, plus the need for an A-frame tongue with clearance for the brackets. If your trailer has outgrown a bumper hitch entirely, the next step up is a bed-mounted setup, and our comparison of fifth wheel hitches covers that ground.
Steel or aluminum, and keeping it secure#
Steel mounts like the B&W, the CURT picks and the Andersen EZ Hitch take abuse and shrug off scrapes. The B&W is the heaviest of them at about 25 lb, while the Andersen keeps a slim profile at 20.6 lb. The Weigh Safe is the only aluminum mount here at 18 lb, so it is the easiest to handle and will not rust, though aluminum scuffs faster where it slides into the receiver.
Either way, buy a locking pin. Ball mounts are one of the most commonly stolen truck parts because they are worth real money and sit in plain view. The Weigh Safe kit includes a keyed lock set, and the others accept any standard 5/8 in receiver lock. A lock also cuts the rattle that a hollow shank makes on rough pavement.
Final recommendation#
Most truck and SUV owners should buy the B&W Tow & Stow. It carries both ball sizes, adjusts for trailer height, folds out of the way when you are done and has the build reputation to last. If you tow one light trailer at one known height, save your money and get the CURT 45056, which arrives with the ball already torqued on. Lifted truck owners should go straight to the Andersen EZ Hitch for its 8 in of drop and slim, certified steel build. If you load your own trailer differently every trip, the Weigh Safe pays for itself the first time its gauge shows the tongue is way off. And if your trailer is big enough to squat the truck or wander at highway speed, skip the ball mount upgrade and buy the CURT 17062 weight distribution kit, because no ball mount can fix a weight problem.
Frequently asked questions
Will these hitches fit my truck?
Every pick here fits a standard 2 in square receiver, which is what most half-ton pickups, mid-size trucks and tow-rated SUVs come with from the factory. Measure the opening in your receiver before you buy. If it is 2.5 in or 3 in, you need the matching version of the same product, not an adapter. If your vehicle has no receiver at all, you need a bolt-on receiver hitch for your exact model first, and only then one of these.
What is the difference between a ball mount and a weight distribution hitch?
A ball mount just holds the ball at the right height. A weight distribution hitch adds spring bars that lever tongue weight off the truck's rear axle and spread it to the front axle and the trailer axles. If your truck squats noticeably when you hook up, or the trailer wanders in crosswinds, you need weight distribution like the CURT 17062. If the truck sits level and the trailer tracks straight, a ball mount is enough.
Which ball size do I need, 2 inch or 2-5/16 inch?
It is set by the trailer's coupler, not by you. Look at the stamp on top of the coupler. Small utility trailers, jet skis and many boat trailers use a 2 in ball. Larger travel trailers, car haulers and heavy equipment trailers usually use 2-5/16 in. If you tow both, buy a mount that carries both sizes, like the B&W Tow & Stow or the Andersen EZ Hitch, instead of two separate mounts.
How much drop do I need?
Park the trailer level, measure from the ground to the bottom of the coupler, then measure from the ground to the top of your receiver opening. The difference is your drop. Most stock trucks need 2 in to 4 in, which the CURT 45056 covers. Lifted trucks often need 6 in to 8 in, which is where the Andersen EZ Hitch earns its place. A trailer towed nose high brakes worse and sways sooner.
Do trailer hitches need maintenance?
Yes, and it is quick. Grease the ball so the coupler does not chew it up, check the ball nut torque a few times a season, and pull the mount out of the receiver now and then to clean out grit and rust. Weight distribution heads like the CURT 17062 have a grease zerk for the spring bar sockets that needs a shot of grease when they start to squeak.
Why do prices range from about thirty dollars to over three hundred?
You are paying for adjustability, ball options and engineering. A fixed steel mount with one ball is stamped and welded in volume, so it is cheap. An adjustable head carries two balls, locks at several heights and has to hold that position under load. A weight distribution kit is a whole system of forged bars, brackets and sway control. Buy based on the trailer you actually pull, not the heaviest thing you might tow one day.
