When your setup is carrying extra weight or towing, body roll can make every turn feel unpredictable. The 1-3/8" diameter Roadmaster rear anti-sway bar ties the rear axle to the chassis so weight transfer stays balanced through corners. Built from thick 4140 chromoly steel, it’s nearly 30 percent more resistant to sway than standard designs, giving you a level, confident feel even on uneven roads or sudden maneuvers.
Crosswinds and passing semis don’t have to wear you out. This system keeps the vehicle steady by cutting side-to-side movement so you’re not constantly correcting the wheel. The bar attaches to the rear axle and chassis, using the axle’s weight to brace the frame as it shifts in turns. You’ll feel more control, less rocking, and far less effort keeping things straight through long highway stretches.
Standard bars made from 1020 steel can twist under pressure; this one uses 4140 chromoly for superior stiffness and strength. Polyurethane bushings replace rubber, resisting oil, gas, and ozone for longer life and consistent support. That means fewer worn-out parts and more years of solid, predictable performance.
This kit bolts right up with the included end links, heavy-gauge mounting hardware, and bushing lubricant—no drilling required. Whether you’re adding it to a stock setup or running airbags or other suspension accessories, it’s designed to fit without interference so you can get it installed and back on the road quickly.

The Roadmaster anti-sway bar has been a tremendous addition to my truck. I carry a 2,500 lb. Lance truck camper in the bed of the truck. Although the truck can easily accommodate the weight of the camper, it is top heavy at a loaded height of 11 to the top of the AC unit. Prior to installing the anti-sway bar, the truck swayed significantly. The anti-sway bar has eliminated excessive sway. On center, the truck will still sway, but as I round a curve, the truck will sway a little bit and then just stop swaying as the anti-sway bar is loaded. It gives me much greater confidence driving around curves at speed. I can typically maintain the same speed as most traffic around me. I highly recommend the Roadmaster anti-sway bar for anyone carrying a truck camper.

Love it so far. The springs are much stronger than the old system. We have had zero problems with the RoadMaster system.

A solid solution for handling and gives my truck a safer feel while pulling massive weight. Very much appreciate the quality of bushings and hardware this came with. It ended any handling problems I was having ...

One year later and I’m very satisfied with this sway bar. My truck rear end feels very “planted” when empty and very stable under heavy loads. Great product for the price and way beefier than Ford’s OEM sway bar.
