Roadmaster anti-sway bars deliver a remarkable improvement in stability and vehicle control for today's most popular motorhome chassis. Kit #1139-163 is an 1-5/8" in diameter and is designed to replace the factory, smaller anti-sway bar for improved stability and handling. This bar is designed to be used ONLY on emergency vehicles due to the rigidity that this anti-sway bar adds to the suspension.

Designed for easy installation, Roadmaster anti-sway bars are made from  cadmium plated 4140 chrome moly steel and ship complete with all necessary mounting hardware, polyurethane bushings and instructions.

INSTALLATION INSTRUCTIONS (For 1139-147 but same installation)

I have a 2002 E450 Ford Class C motorhome will the Roadmaster sway bar 1139 - 163 work without issues. Write up indicates for emergency vehicles only? Thanks ( Jesse Valdez, 02/07/2018 )
It would fit but Roadmaster does not recommend using it as it will make the suspension too stiff in an RV application. ( Support )
