SuperPro - sprSPF0821K - Ford Mustang Rear Spring Bushings

There are 3 size/dimension options for early Mustang rear leaf spring bushings. Dimensions on this kit: O.D. : 35mm Length : 31mm I.D. : 12.7mm These bushings are often overlooked when upgrading the suspension of a 4WD. Leaf spring bushings stabilize the movement of the rear axle. Inferior, worn or damaged bushings in this area will cause the solid rear axle to move and impart rear end passive steer to the vehicle. It also causes the vehicle to "wander" all over the road and be unstable under heavy braking. This can be especially noticeable carrying a load or towing a boat, RV or any significant trailer. The OE rubber bushings are designed to work at standard ride height with standard wheels and tires and with standard loads. By fitting SuperPro Bushings the rear end of your 4WD will handle just about anything you can throw at it!

SuperPro rear leaf spring bushings are designed for early Ford Mustang applications and help stabilize rear axle movement. Worn, damaged or inferior bushings can contribute to rear-end passive steer, wandering and instability during heavy braking, particularly when carrying a load or towing.

These bushings use an outside diameter of 35 mm, a length of 31 mm and an inside diameter of 12.7 mm. The product data identifies three size options for early Mustang rear leaf spring bushings; these dimensions apply to this kit. SuperPro bushings are intended to improve rear suspension control compared with standard OE rubber bushings when used at standard ride height with standard wheels, tires and loads.
