If your trailer feels heavy on the tongue or causes the back end to sag, this Reese trunnion bar system levels things out. It evenly spreads your tongue weight—rated for 200 lbs to 600 lbs—across all the axles so you can safely tow up to 6,000 lbs. That balance restores steering and braking control, keeping your ride smooth and predictable even with a full load.
Old-style washer stacks can make setup a hassle, but this system keeps things simple. The Reese head uses exterior serrated washers that let you dial in the tilt without disassembling the hitch. Loosen, adjust, and tighten—it’s quick, secure, and doesn’t require any special tools or multiple washers piled on a pin.
This setup starts as pure weight distribution, but it’s built to grow with your towing needs. If you notice sway down the line, just add Reese’s Strait-Line dual-cam sway control (RP26002 – sold separately) for active correction that helps during cornering and crosswinds. Or go with a bar-style friction sway control (83660 – sold separately) for a simpler add-on that lets you fine-tune tension with a turn of a handle.
Everything you need for the core setup comes in the box—head assembly, lift brackets, trunnion spring bars, lift chains, and hardware—all fitting standard 2" x 2" trailer hitch receivers rated for weight distribution use. The system mounts about 30" back from the hitch ball and needs around 5-1/2" of clear frame space. The adjustable shank and hitch ball with a 1-1/4" diameter threaded shank are sold separately so you can match them exactly to your trailer setup.
Once properly adjusted, users report that long drives transform from white-knuckle tension to comfortable control. The smoother handling and balanced load mean less rocking or bouncing at highway speeds—so you can focus on the drive instead of fighting the trailer.

Ive used this on 10K houseboat trailers and 7.5K campers, this is the one you are looking for. The adjustable head makes all the different in adjusting weight between front and rear truck axles. It really does remove over understeer on the truck when set correctly. This was tested from 60 - 75 MPH, no death wobble. Purchase the anti-sway arms, after one good wind sheer, your nerves will thank you.

We are about to make our second long haul pulling our 8000lb travel trailer. Our Reese hitch makes all the difference between nail bitting and a relaxed trip. Still 5 stars

Still happy with the system. I unhook the cams and spring bars just a couple miles away from our campsite because they recommend not backing up with them attached. Even that short distance I can feel a difference with the trailer moving around.
