Keep the rear leaf spring located and cushioned with the Mevotech Supreme Leaf Spring Bushing MS504188. It installs at the rear fixed end, rear forward position, isolating the leaf spring eye from its mounting bracket so the spring can pivot while road shock and vibration are dampened. It fits a wide range of classic Chevrolet and GMC trucks and vans, including the 1973-1991 Chevrolet Blazer and 1979-1996 Chevrolet G30 — see the "Vehicles it fits" section for the full list.
Over time the original rubber can crack, dry out or separate, allowing extra movement, clunks or a harsher ride. If a worn leaf spring bushing is the cause, this direct-fit replacement is designed to restore proper cushioning and location for the listed applications.
