Restore your Fox Body Mustang's front suspension geometry and ride quality with Prothane's polyurethane front upper spring isolators. The factory rubber isolators compress, crack, and deteriorate over time, allowing the spring to shift and introducing noise, harshness, and imprecise handling into an otherwise sorted suspension. These direct-replacement isolators restore the correct interface between the spring and the upper mount, delivering consistent performance that rubber simply cannot sustain.
Polyurethane construction outperforms rubber. Prothane's polyurethane compound resists oil, ozone, and temperature extremes that cause OEM rubber to degrade. The material holds its shape under load, keeping the spring seated correctly and maintaining predictable spring rates throughout the suspension travel.
A direct fit for 1979-1982 Fox Body Mustangs. These isolators are engineered specifically for the front upper spring perch on the Fox Body platform. No trimming or modification required; they drop into the factory location and restore the correct spring-to-mount relationship immediately.
Available in Red or Black. Choose the finish that suits your suspension aesthetic. Both colors use the same polyurethane compound and carry the same performance characteristics.
