Product Description

The Prothane 6-1053 kit is engineered to replace the worn rubber rear leaf spring eye and shackle bushings on classic Ford Mustangs from 1964 through 1973. Excessive movement or deterioration in these pivot points can lead to sloppy rear suspension feel, poor handling, and premature wear of related components. Prothane's polyurethane components restore tightness and control while offering improved durability over factory rubber.

This kit is ideal for restoration enthusiasts, street performance builds, and even mild track use - especially where the original rear leaf springs have been installed for decades. Installation is straightforward for a correctly supported rear axle: remove the old bushings, install the new precision sleeves and polyurethane parts, torque the shackles to spec, and re-check after a few miles. Because this is a direct-fit application for the 64-73 Mustang, no modifications are required.
