Roadmaster Heavy Duty 1-3/4" Rear Auxiliary Sway Bar Kit for 2006-Current Ford F53 Class A Motor Homes (Part Number 1139-212)

Roadmaster anti-sway bars deliver a noticeable improvement in vehicle stability and handling for today’s most popular motorhome chassis. The Roadmaster 1139-212 kit features a 1-3/4" diameter rear auxiliary sway bar meaning you retain the factory rear sway bar and install this one in addition. 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.

Applications:

• 2006-2020 Ford F53 V10 20,500-22,000 GVWR but we recommend 1139-145 as it's an easier installation

• 2006-2020 Ford F53 V10 24,000-26,000 GVWR

• 2021-Current Ford F53 V8 16,000-26,000 GVWR

Special Notes:

• Does not fit Toy Hauler motor homes such as Thor Outlaw

• Installs with a flat plate that is held in place by the leaf spring u-bolts on the rear axle. Check to ensure there enough exposed u-bolt below the nut to accommodate the factory nut and washer once the 1/2" tick plate is installed above them. If there is not enough exposed u-bolt, will need to purchase longer u-bolt kit 590050-00 for square top style or 590050-10 for round top style.
