Rear spring bump stop for selected Toyota 4Runner, Toyota FJ Cruiser, Toyota Land Cruiser Prado and Lexus GX vehicles. Designed for installation on either the left or right side of the rear suspension. Two bump stops are normally required per vehicle. NBR 48306-60180N works together with the rear coil spring and shock absorber to limit excessive suspension compression. Its durable rubber construction helps absorb impacts, prevent metal-to-metal contact and protect suspension components when driving over bumps or carrying increased loads. Manufactured according to original dimensions for direct installation without modifications. Suitable primarily for vehicles equipped with standard rear coil spring suspension. Always verify compatibility by VIN, OE number, chassis code and suspension configuration before installation.
