Rear control arms are a crucial suspension upgrade for your GM vehicle. Stock control arms can cause traction loss and poor handling due to bushing deflection and weak material. Our tubular control arms offer the best of both worlds for weekend cruisers or track enthusiasts. The polyurethane bushings provide an upgrade over OEM rubber bushings, improving ride quality and reducing traction loss. These control arms are a direct bolt-on replacement that minimizes wheel hop, enhances cornering, and improves track consistency. Installation is easy with a 1-hour bolt-on process that requires no drilling and uses OEM hardware. The control arms are constructed of 1.625" OD x 0.125" DOM Mild Steel Tubing with CNC machined 0.250" Mild Steel Mounting Plates. They also feature "On-Car" Grease-able Bushings, Zerk Grease Fittings, and a durable powder coat finish.
