Construction & Design:

The Prothane coil spring isolator is manufactured from premium-grade polyurethane, a material known for its excellent resilience and ability to absorb shocks and vibrations. Unlike traditional rubber isolators that can degrade and crack over time, polyurethane maintains its shape and performance under harsh off-road conditions and temperature extremes.

Engineered to exact specifications, this isolator fits snugly between the coil spring and the spring perch, providing a stable cushion that prevents metal-to-metal contact. The design ensures consistent lift height and helps preserve the integrity of the suspension components by minimizing wear.

Installation & Fitment:

Installation of the Prothane 1-inch Lift Coil Spring Isolator is straightforward and can typically be completed with basic hand tools. It is designed to fit directly onto the coil springs of Jeep Wrangler models from 1997 through 2006, including popular trims such as the Rubicon, Sahara, SE, Sport, Unlimited, and X. No cutting, welding, or complex modifications are necessary, making it an ideal upgrade for DIY enthusiasts and professional installers alike.

By adding this isolator, you achieve a reliable lift that improves off-road capability and tire clearance while maintaining factory suspension geometry and ride quality.
