When rubber axle housing bushings wear out, crack, and compress over time, they let the rear axle shift under hard acceleration and cornering. Prothane's polyurethane rear control arm axle housing bushing kit firms up that connection on 1979-2004 Mustangs, restoring predictable rear axle location without the compliance built into factory rubber.
Polyurethane construction holds its shape. Unlike rubber, polyurethane resists compression set, oil contamination, and the heat cycles that cause factory bushings to deteriorate. The rear axle stays planted where it's supposed to be, translating throttle inputs and steering corrections into clean, consistent movement.
Shells not included. This kit supplies replacement bushings only, designed for applications where the existing metal shells are still serviceable. Reusing sound shells keeps the job cleaner and avoids unnecessary press work on a solid housing.
Grease is in the box. Prothane includes Super Grease with the kit, so the bushings install properly lubricated and articulate without squeaking over the life of the part.
Color choice lets you match your build. Both red and black bushings are available, so the install matches your desired aesthetic under the car.
