Construction & Design:

The Prothane coil spring isolator is crafted from high-quality polyurethane, a material known for its exceptional durability and resilience under demanding conditions. Unlike traditional rubber isolators, polyurethane maintains its shape and cushioning properties over time, resisting deterioration from exposure to oil, road salts, and extreme temperatures.

Its precision-molded design ensures a snug fit around the coil spring, effectively isolating metal-to-metal contact points that cause noise and premature wear. The vibrant red color not only signifies Prothane’s commitment to quality but also adds a visual upgrade to the suspension components.

Installation of the Prothane Red Coil Spring Isolator is straightforward and designed for ease of use. It is a direct replacement for factory isolators on Jeep Wrangler models from 2007 through 2012, including both standard and Unlimited versions. No special tools or modifications are necessary, making it an ideal upgrade for DIY enthusiasts and professional installers alike.

This isolator is engineered to work seamlessly with 2-inch lift coil springs, ensuring proper suspension geometry and ride height without compromising vehicle handling or safety.
