Nothing makes a drive more tiring than a trailer that’s heavy on the tongue and light on control. The Curt Trunnion Style Weight Distribution System spreads your load evenly across all axles so your setup stays level and predictable. With a 10,000-lb maximum gross towing weight and 1,000-lb maximum tongue weight, it restores balance and stability to your ride. You’ll notice the improvement right away—less bounce, less squat, and better steering response when your trailer is hitched up.
This system is made to take real use on the road. The trunnion spring bars are constructed from solid, forged steel for long-term strength and durability. Every component is powder coated to resist corrosion, so it can handle years of hauling in the elements. The result is a hitch that stays tight, keeps its alignment, and always pulls straight, even when loaded near capacity.
Getting the right tension doesn’t have to be a chore. The head tilt adjusts easily with two set screws—no stacking washers or disassembling parts. A snap-up lever helps you lift the chains into place without straining or cranking the jack too far. Once it’s dialed in, the hitch levels out your trailer perfectly, letting you tow confidently every time you hook up.
If you want to add sway control later, the system is ready for it. It’s built to accept an optional bar-style friction sway control kit (part 17200, sold separately). This lets you tune how much resistance the trailer applies when wind or passing traffic tries to push you off line. You can add one bar or two, depending on your trailer length, and adjust the tension by turning a simple handle.

Everything you need for the weight distribution side comes in the box—head assembly, adjustable shank, spring bars, lift brackets, lift chains, handle, and all required hardware. The shank gives up to 7-1/2" of rise or 1/2" of drop to help you find your trailer’s sweet spot. A hitch ball with a 1-1/4" diameter shank is sold separately so you can choose the correct size for your coupler. This system is a solid, dependable choice for towing that feels balanced, smooth, and secure.

Still working well. I did damage one hitch head in the first year, but know now to disconnect the bars before backing up. A $73 mistake, but still happy.

Fantastic hitch, worth every penny. You might need longer safety chains due to the added length.

OK...five stars now. One year later and Im very happy with this system. Easy to and reinstall when were camped. Hitch weight on my A-frame pop up is about 350lb empty so it ped my Terrain about 3. A level ride is much better.
Do you have a question about this Weight Distribution Hitch?
