Nothing unsettles a drive like feeling the front end lean through corners or shift when a gust hits. This 1-3/4" diameter Roadmaster front anti-sway bar ties the axle to the chassis to balance weight transfer and keep things level through curves and lane changes. Made from thick 4140 chromoly steel, it’s tougher than standard steel and resists flex, so the vehicle tracks straighter with less body roll.
Crosswinds and passing traffic don’t have to mean constant corrections at the wheel. By minimizing side-to-side sway, this front bar makes steering steadier and driving less tiring. The result is a level ride that keeps you confident and relaxed mile after mile.
Instead of soft rubber that squishes out over time, this setup uses polyurethane bushings that hold up against oil, gas, and ozone. They keep their shape, maintaining tight, consistent support. The included heavy-gauge mounting hardware and thick chromoly bar combine for a durable system that keeps its strength and performance run after run.

Getting stability shouldn’t mean tearing into your frame. This bar bolts directly to the axle and chassis using the supplied hardware and lubricant for the bushings—no drilling needed. It’s a clean, secure install that fits around most popular suspension add-ons and complements rear sway bars and steering stabilizers for a solid all-around setup.

Sounds like it helped take away a lot of stress when driving your RV, Leslie. Sometimes adding in a rear sway bar can also help with driving in the wind even more, if you ever feel like maybe you want a little more support in that category.

The difference after installing the Road Master antisway bar has been night and day. The motorhome handles so much better on the road and Im not so much exhausted at the end of the day after Driving. There is a huge difference during windy conditions and I hardly feel it when passed by semi-trucks.
