The SuperPro rear upper spring seat bushing set for 2008 Pontiac G8 upgrades coil spring interfaces with polyurethane components that outlast rubber insulators. These parts maintain correct spring location and retention, reducing sag and softening over time. Developed and manufactured in Australia from a tested polyurethane blend, the insulators improve handling consistency, preserve ride height, resist fluids and temperature extremes, and come with a lifetime warranty.
