Ford E350 and Ford E450 Class C Motorhome Suspension, Steering, and Handling Upgrade

Roadmaster anti-sway bars deliver a noticeable improvement in vehicle stability and handling for today’s most popular motorhome chassis. The Roadmaster 1139-147 kit features a 1-1/2" diameter rear sway bar that replaces the smaller factory rear sway bar and includes heavy-duty polyurethane bushings for enhanced control and reduced body roll.

Designed for straightforward installation, Roadmaster anti-sway bars are precision-engineered from powder-coated 4140 chromoly steel and paired with high-performance polyurethane bushings for maximum durability and long-lasting support beyond factory components. Each kit includes all required mounting hardware, upgraded polyurethane bushings, and detailed installation instructions.

What is the best front and rear sway bars to purchase for my 2022 Entegra Odyssey 26M on a Ford E450 chassis. Thank you. ( Barbara, 08/28/2024 )
Hello Barbara, that calls for the 1139-147 and 1139-176 ( fits the 2022's as well) 
will this rear sway bar fit a 2017 Thor Axis 24.1 RUV. E450 Ford v10 ( Dan, 12/22/2016 )

Dan,

Yes this will fit. The E450 chassis that the RUV's use are no different from an E450 used for Class-C's.
