Maximize traction and rear suspension predictability on your 1979-2003 Ford Mustang with Prothane Rear Control Arm Axle Housing Bushings (Part #6-309). Soft, aging factory rubber bushings allow excessive axle twist and unpredictable rear-end sway during aggressive shifts and heavy acceleration. Built from hard-durometer polyurethane, these high-performance bushings lock down axle housing alignment for direct power transfer to the pavement. Supplied without outer metal shells for straightforward press-in installation into original housings, this kit is offered in both red and black to deliver superior control, chemical resistance, and long-term durability.
