Description
Upgrade your Ford F-150's rear suspension with the SuperPro Rear Leaf Spring & Shackle Bushing Kit. Leaf spring bushings help stabilize rear axle movement, making them an important component when upgrading a 4WD suspension.
Inferior, worn, or damaged bushings can allow the solid rear axle to move and contribute to passive rear-end steering. This can cause the vehicle to wander on the road and feel unstable during heavy braking. These effects may be particularly noticeable when carrying a load or towing a boat, RV, or other significant trailer.
Original equipment rubber bushings are designed to operate at standard ride height with standard wheels and tires, and under standard load conditions. Installing SuperPro bushings helps support rear-end stability and suspension performance across a variety of driving and load conditions.
SuperPro polyurethane bushings are developed using nearly five decades of suspension expertise and experience in Australia's harsh terrain. Engineered with durability as a key consideration, they are also designed to maintain ride and passenger comfort. Their material composition retains OEM levels of noise and harshness isolation while delivering improved performance and road manners.
