This Energy Suspension rear subframe bushing set is a street-performance polyurethane kit for 2004–2006 Pontiac GTO applications. Made from Energy's Hyper‑Flex polyurethane, the kit replaces worn rubber bushings to restore cab and subframe alignment, reduce wheel hop and improve suspension stability. Many sets include a zinc-plated steel ring molded in for added durability.
