Roadmaster Stabilizer Bar (MPN: 1139-189)

Enhance RV stability and cornering control with advanced design.

The Roadmaster Stabilizer Bar is engineered to improve the handling and stability of your RV, specifically designed for select Ford E-350 and E-450 motorhomes from 2009 and onward. With a front bar diameter of 1-3/8 inches, this solid sway bar is constructed from high-grade 4140 chromoly steel, ensuring durability and performance. The use of polyurethane bushings enhances pivot points, providing superior resistance to gas, oil, and ozone corrosion compared to traditional rubber bushings.

This stabilizer bar features a baked-on powder-coated finish, which not only adds to its aesthetic appeal but also protects against wear and tear. The installation process is straightforward, estimated at approximately 1.5 hours, and includes all necessary mounting hardware. By upgrading to the Roadmaster Stabilizer Bar, RV owners can expect improved cornering control and a more level ride over uneven terrain, contributing to a more enjoyable driving experience.
