Improved spring performance
Prevents unwanted suspension noise
What's in the Box
(2) Lower Spring Isolators
Reduce Suspension Noise
These Prothane lower spring isolators are located between the rear spring and the control arm on your 1999-2004 SVT Cobra. Over the years, these isolators wear and tear leaving you with a harsh ride and a squeaky suspension. Get your Cobra riding smoothly and quietly again with a new set of Protane rear spring isolators. These isolators help to dampen road noise and suspension vibrations.
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.
