Poly Coil spacer 30mm of lift. Sold single. Dobinsons Spring & Suspension offer these quality polyurethane coil spacers, designed to add additional lift to your vehicle if your coil springs have sagged or lost height over time. Sold individually, each spacer is intended to be mounted between the coil seat and the original coil isolator, to avoid any possible noise issues. NOTE: Adding coil spring spacers to the vehicle may cause "coil bind" (all coils closed together) before the bump stop comes into effect. This can cause very serious damage to the spring and/or suspension components. Please consider this before ordering.
