Energy Suspension 21.3102G Rear Lower Control Arm Bushing Set - Black Polyurethane

The Energy Suspension 21.3102G is a rear lower control arm bushing set crafted from Energy Suspension's proprietary Hyper-Flex performance polyurethane. Designed as a direct-fit replacement for the remaining stock control arms, this set delivers superior alignment retention and handling precision compared to factory rubber bushings. Polyurethane's inherent resistance to oils, solvents, and heat means these bushings maintain their geometry and compliance properties far longer than OEM rubber under real-world driving conditions.

• Maintains proper alignment under demanding street and track conditions
