Improve stability, reduce body roll, and drive with more confidence. The Roadmaster Rear Anti-Sway Bar is built to reduce side-to-side sway and help your Ram ProMaster 2500/3500 stay steady—even in crosswinds, sharp turns, or with shifting cargo.
This heavy-duty bar mounts directly to the rear axle and chassis, using the axle’s weight to brace the frame during movement. The result: better control, smoother handling, and less fatigue behind the wheel.

Why It Works:
Like quality shocks control vertical movement, this sway bar controls lateral movement. It links the chassis to the rear axle and uses torsional resistance to counteract sway. The polyurethane bushings allow precise flex, absorbing motion without giving in to it.
If you want tighter handling, less sway, and a more relaxed driving experience—this is the upgrade your ProMaster needs.
