Prothane Rear Coil Spring Isolators for 1979-2004 Ford Mustang

Ensure a quiet and smooth ride in your Ford Mustang with the Prothane Rear Coil Spring Isolator. Designed to fit a wide range of Mustang models from 1979 through 2004, this black isolator is crafted from high-performance polyurethane to effectively cushion the rear coil springs. This prevents metal-on-metal contact, which can cause noise, vibration, and damage to your suspension components.

Why Choose Prothane Isolators?

  • Broad Fitment: Compatible with numerous Mustang trims including Base, GT, LX, Cobra, SVO, and more, spanning from the Fox Body era to the SN95 generation. Also fits Mercury Capri models from the same period.
  • Noise Reduction: Effectively dampens noise and vibration generated by the rear coil springs, leading to a more comfortable driving experience.
  • Component Protection: Acts as a protective barrier between the spring and its mounting point, preventing wear and potential damage.
  • Durable Polyurethane: Made from Prothane's signature durable polyurethane material, known for its resistance to abrasion, chemicals, and extreme temperatures.
  • Black Finish: Provides a clean, stealthy look within the suspension assembly.

These isolators are a small but crucial component for maintaining the integrity and comfort of your Mustang's rear suspension. Whether you're restoring a classic or upgrading a modern muscle car, Prothane's quality ensures a reliable and long-lasting solution. Easy to install, they offer a significant improvement in ride quality and component longevity.

Upgrade your Ford Mustang's rear suspension with these essential Prothane isolators. Experience a quieter, more refined ride. Find them at GGCRACING.
