Energy Suspension Hyper-Flex master bushing set for the 2004 Pontiac GTO replaces factory rubber bushings with Hyper-Flex polyurethane components across front and rear control arms, sway bars, and rear subframe locations. Made in the USA, these bushings resist oils, UV, and environmental degradation, improve suspension stability and handling, and are intended as a long-lasting upgrade over stock rubber components.
