Weight distribution hitches that handle travel trailers
Weight distribution hitches with built-in sway control for bumper-pull travel trailers, ranked by capacity and how well each one handles wind and crosswind.
For a bumper-pull travel trailer over 5,000 lb loaded, you want a weight distribution hitch with built-in sway control. The four-point Equal-i-zer remains the workhorse choice. Blue Ox SwayPro, Curt TruTrack 4P, Andersen No-Sway, and Husky Center Line TS are also good. Hensley and ProPride are the premium upgrades for serious tow setups.
A regular ball mount and hitch is fine for a 3,500 lb utility trailer. A travel trailer with 600 to 1,200 lb of tongue weight pulls the rear of the truck down, lifts the front, ruins the steering, and makes sway worse. Weight distribution shifts that load forward.
What weight distribution actually does
A weight distribution hitch (WDH) uses spring bars to transfer some of the tongue weight back to the trailer’s axle and forward to the truck’s front axle. The result: the truck sits more level, steering improves, and the trailer is less prone to sway.
Built-in sway control adds friction or geometry that resists side-to-side movement. The trailer can’t wag the truck.
| Hitch | GTW rating | Sway control | Approximate price | Notes |
|---|---|---|---|---|
| Equal-i-zer 4-Point | 4,000 to 16,000 lb | 4-point friction | $500 to $750 | Industry standard. Noisier than some |
| Blue Ox SwayPro | 4,000 to 15,000 lb | Spring bars + sway control | $550 to $850 | Quieter than Equal-i-zer |
| Curt TruTrack 4P | 8,000 to 14,000 lb | 4-point friction | $450 to $700 | Most affordable in this tier |
| Andersen No-Sway | 4,000 to 16,000 lb | Spring/chain tension | $700 to $900 | Lightweight, easy to install |
| Husky Center Line TS | 8,000 to 12,000 lb | Integrated sway control | $400 to $600 | Good ground clearance |
| Reese Strait-Line | 6,000 to 15,000 lb | Dual cam sway | $450 to $700 | Older reputation but still solid |
| Hensley Arrow | up to 14,000 lb | Geometric sway elimination | $2,500 to $3,200 | Premium. Eliminates sway by design |
| ProPride 3P | up to 16,000 lb | Geometric pivot point | $2,500 to $3,400 | Same designer as Hensley |
When to use what
Loaded trailer under 5,000 lb: A standard ball mount might be enough. Add sway control as an aftermarket accessory if the trailer is tall or you tow in windy areas.
Loaded trailer 5,000 to 10,000 lb: Weight distribution hitch with built-in sway control. This is where Equal-i-zer, Blue Ox, Curt TruTrack, Andersen, and Husky live.
Loaded trailer 10,000 to 15,000 lb: Same hitch tier but sized for the higher GTW. Pay attention to tongue weight rating, not just GTW.
Big rigs, frequent towing, or notoriously sway-prone setups: Hensley or ProPride. Geometric sway elimination instead of friction. Costs three times as much, eliminates sway entirely.
Hitch class vs the WDH rating
The hitch class on your truck (receiver tube) and the WDH GTW rating are separate numbers, both of which must be at or above your loaded trailer weight.
- Class III: up to 8,000 lb GTW, 800 lb tongue weight without WDH, 10,000 lb with WDH
- Class IV: up to 10,000 lb GTW, 1,000 lb tongue weight, 12,000 lb with WDH
- Class V: up to 20,000+ lb GTW
Most factory hitches on half-ton trucks are Class IV. Aftermarket Class IV hitches from Curt, Reese, or Draw-Tite are easy bolt-on jobs for $200 to $400.
How to size a WDH to your trailer
Two numbers:
- Trailer GTW (loaded, not dry): pick a hitch where the GTW rating is comfortably above your loaded trailer weight. Don’t size at the limit.
- Tongue weight (10 to 15% of loaded GTW): pick spring bar size that matches. A 10,000 lb trailer with 1,200 lb tongue weight needs spring bars in the 1,000 to 1,400 lb range. Too-stiff bars don’t flex on uneven roads, too-soft bars don’t redistribute weight.
Example: Forest River R-Pod loaded to 4,200 lb with 420 lb tongue weight. Pick a 6,000 lb GTW / 600 lb TW hitch. That’s a small Equal-i-zer or Blue Ox SwayPro.
What people forget
- Hitch height needs to match the trailer. A drop or rise shank gets the ball at the right height so the trailer rides level. Level matters for braking, tire wear, and headlight aim.
- Spring bars need to be torqued correctly. Too loose and they don’t transfer weight. Too tight and the truck rides hard or the bars chain links lift.
- The friction pads on Equal-i-zer hitches wear. Replace them every couple of years if you tow often.
- Lubrication matters. Spring bar sockets need grease. Without it, you get the “clunk on turns” that Equal-i-zer owners complain about.
Fifth wheel and gooseneck (a different conversation)
If your trailer is a fifth wheel or gooseneck, you don’t use a weight distribution hitch. You use a fifth wheel hitch (B&W Companion, Curt A20, Reese Goose Box) or a gooseneck ball, both mounted in the truck bed.
B&W is the brand that owns this segment. Their Companion fifth wheel hitch installs into a gooseneck ball mount, which keeps the bed clear when you’re not towing.
Installation: DIY or shop
WDH installation on the trailer side is straightforward: bolt the head to the trailer A-frame, hook up the spring bars. The truck side connection is just sliding the ball mount into the receiver. The trick is getting the geometry right (drop/rise, head tilt, spring bar tension) so the truck and trailer sit level.
If you’re new to this, pay a shop $100 to $200 to set it up the first time. Watch them do it, then you can adjust it yourself afterward. The geometry isn’t intuitive until you’ve seen it done.
Common mistakes
- Buying a WDH that’s the right GTW but wrong tongue weight rating. The two ratings are different.
- Setting the spring bars too high or too low. The truck and trailer should be parallel to the road when hitched.
- Forgetting sway control entirely. A travel trailer over 5,000 lb without sway control is a bad day waiting for a windy stretch of highway.
- Putting the WDH on a trailer that doesn’t need one. A 2,500 lb utility trailer doesn’t need weight distribution. Save the money.
A note for Ford owners in 2026
Ford recall 26C10 (NHTSA 26V104000) covers 2021 to 2026 F-150, 2022 to 2026 Super Duty, 2024 to 2026 Ranger, 2022 to 2026 Expedition, 2022 to 2026 Maverick, 2022 to 2026 Lincoln Navigator, and 2026 Transit. The Integrated Trailer Module software fault disables trailer brake lights, turn signals, and electric trailer brakes at startup. No hitch in the world fixes a fault in the trailer brake controller. Check FordPass before towing. OTA fix started rolling out in May 2026.
