The Energy Suspension Hyper-Flex master bushing set for 1986–1991 Mazda RX-7 is a red performance polyurethane kit that replaces multiple suspension bushings. Hyper-Flex material resists oils, coolants and UV exposure, outlasting rubber up to five-to-one. The set includes front and rear control arm bushings, sway bar bushings, and boots to improve handling, maintain alignment and reduce wheel hop under hard acceleration.
