Description
Upgrade the rear suspension of your 4WD Ford F-150 with the SuperPro Rear Leaf Spring Shackle Bushing Kit. Leaf spring bushings help stabilize rear axle movement. Worn, damaged, or inferior bushings can allow the solid rear axle to move, causing passive rear-end steering, road wandering, and instability during heavy braking. These issues can become especially noticeable when carrying a load or towing a boat, RV, or other significant trailer.
Original equipment rubber bushings are designed for standard ride height, wheels and tires, and load conditions. Replacing them with SuperPro bushings helps improve rear-end stability and provides suspension support for a wide range of driving and load conditions.

- Helps stabilize rear axle movement.
- Helps reduce unwanted axle movement that can contribute to passive rear-end steering.
- Helps address wandering and instability under heavy braking.
- Designed for rear leaf spring shackle applications.
- Suitable for suspension upgrades on 4WD vehicles.
