Energy Suspension coil spring isolator set for GM applications is a direct-fit polyurethane replacement that installs like OEM and preserves factory ride. Made from Hyper-Flex™ material, these red isolators last three to ten times longer than rubber, resist wear, and can provide a small increase in ride height. They offer a durable, low-maintenance way to reduce spring noise and prolong service life.
