SuperPro Ford Mustang Rear Spring All

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!

Upgrade the rear suspension of your classic Ford Mustang with SuperPro SPF0821K rear leaf spring bushings. Designed for select 1967 through 1973 Mustang applications, this bushing kit helps stabilize rear axle movement and supports more predictable handling. Replacing worn, damaged, or inferior original-equipment rubber bushings can help reduce unwanted rear-end movement and passive steer that may cause the vehicle to wander or feel unstable on the road.
SuperPro polyurethane bushings are engineered to provide improved control over the rear leaf spring assembly compared with standard rubber components. The original bushings are designed for factory ride height, standard wheels and tires, and typical vehicle loads. SuperPro SPF0821K bushings are a practical suspension upgrade for drivers who regularly carry additional weight or tow a boat, recreational vehicle, or trailer. Improved bushing control can help maintain more consistent rear suspension behavior during braking, cornering, acceleration, and loaded driving.
This kit is available in multiple application-specific sizes for early Ford Mustang rear leaf spring systems. The SPF0821K configuration uses a 35 mm outside diameter, 31 mm length, and 1/2-inch inside diameter. Verify the vehicle application and existing suspension configuration before ordering to ensure the correct fit. The kit is intended for automotive suspension service and includes one set of SuperPro rear spring bushings for the specified application.
SuperPro combines durable polyurethane construction with application-focused suspension design to help restore confident handling in classic Mustang builds. Whether refreshing a stock-style suspension or supporting a broader performance upgrade, these rear leaf spring bushings provide a dependable replacement for deteriorated factory components while helping keep the rear axle properly controlled.
