When installing lowering springs or replacing control arms, many Mustang enthusiasts will also find they have worn out rubber spring isolators. BBK Polyurethane Rear Coil Spring Isolators prevent the steel springs from touching the chassis directly which can cause annoying noises to transmit through the chassis. BBK high quality polyurethane direct replacement isolators will not stretch or crack.
Compatible with Stock or Aftermarket Springs
BBK coil spring isolators are the same diameter and thickness as the factory ones, so they fit right into place and have no affect on ride height.
