Roadmaster 1-1/2" Polyurethane Rear Sway Bar Bushing Kit for 2016-2019 Ford F53 Class A Motorhome (Part Number 4139-126)

Complete Polyurethane Front Sway Bar Bushing Kit Upgrade

Replace worn factory rubber sway bar bushings with durable polyurethane bushings designed to deliver improved stability, tighter handling, and long-lasting performance. Unlike rubber, which deteriorates over time due to heat, oil, fuel exposure, and road contaminants, polyurethane maintains its shape and strength which provides a more controlled, confident ride for years to come.

These replacement bushings work with your existing factory anti-sway bar to reduce body roll, improve cornering stability, and restore proper sway bar function. The flexible polyurethane design enhances handling without making the suspension overly rigid. Part # 4139-126 lets you replace the old sway bar bushings without having to replace the entire sway bar for an upgrade in handling.

Applications:

• 2016-2019 Ford F53 Class A Motorhome

• For 1-1/2" diameter sway bars

• Direct replacement for factory rubber sway bar bushings

Special Notes:

• Be sure to measure your existing sway bar! Verify your anti-sway bar is 1-1/2″ (some are 1-3/8″ or 1-5/8″, etc...)

• When installing polyurethane bushings, it’s common practice to apply a bit of grease or lube on the inside of the bushing so the sway bar can move smoothly inside without premature wear.

• Some end link components may not be used.
