Enhance the stability and traction of your 1979-2004 Ford Mustang with Prothane's Hard polyurethane axle housing bushings. These red bushings are designed to replace the stock, often overly flexible, rubber components that connect the rear axle housing to the chassis. By minimizing differential movement and axle deflection, Prothane bushings ensure that power is delivered more effectively to the wheels, improving acceleration, braking stability, and overall rear-end control, especially under load or during aggressive driving maneuvers.
For a more planted and responsive rear suspension, choose the Prothane 79-04 Ford Mustang Axle Housing Bushings. Available now at GGCRACING.
