Restore quiet suspension operation and protect your chassis with the Prothane Black Polyurethane Coil Spring Isolator Set (Part #6-1701-BL) for 1979-1999 Ford Mustang and 1979-1986 Mercury Capri models. Factory rubber spring pads deteriorate, rot, and compress over time, leading to harsh metal-on-metal spring contact, annoying squeaks, and uneven ride height. Formulated from premium black polyurethane, this set of 4 isolators cushions coil springs, dampens road noise, resists oil and weather breakdown, and maintains consistent suspension alignment.
