1979-2004 Mustang Urethane Spring Isolator Kit
Replace your stock, worn-out rubber spring isolators with this 1979-2004 Mustang urethane spring isolator kit! The main purpose of the spring isolator is to reduce noise associated with the suspension while going through its normal range of motion. Over time, your factory spring isolators start to crack and break, leaving you with a rough ride, popping or creaking noises during load shifting. If the spring isolators are missing, you would have metal-to-metal contact, which would produce unwanted creaking and popping in the rear suspension during load shifting. Prothane's urethane isolators feature a polyurethane construction that's built to last. Polyurethane is more durable than your factory rubber isolators and will not dry out or crack!
 
Ride Height Note
  • Due to the urethane construction, these isolators may affect the final ride height of your vehicle.

About This Brand


Prothane

Lifted or lowered suspensions, increases in horsepower, plus-size wheels and tires can subject traditional rubber suspension bushings to forces beyond their limits. Control arms, strut arms, leaf springs, body mounts, motor mounts, transmission mounts, sway bars and shocks all control movement and maintain alignment but the rubber bushings they use are designed for more "middle of the road" use. Rubber also deteriorates over time, further reducing control. This contributes to premature component failure, a "spongy" ride and less than ideal performance handling. Urethane bushings can correct these conditions, and improve drivability in your Mustang or Ford Lightning.
