Energy Suspension red rear control arm bushing set for 1963–1972 GM C-10/C1500 and 1967–1972 C-20/C2500 uses Hyper-Flex polyurethane to improve handling and alignment over rubber. Intended to fit into remaining stock control arms, the full-floating design reduces binding and increases durability under street, track or off-road use. These replaceable bushings aim to provide firmer, longer-lasting suspension response.
