Rear control arms are essential suspension upgrades for your GM vehicle. Stock control arms are prone to bushing deflection, rust, and weak material, leading to traction loss and poor handling. Our tubular control arms offer a solution for both weekend cruisers and track enthusiasts. The polyurethane bushings included provide better performance than OEM rubber bushings, reducing traction loss and improving ride quality. These control arms are easy to install and help minimize wheel hop, enhance cornering, and ensure track consistency. Sway bar mounting holes are also included for both stock and aftermarket bars. Installation is quick and easy using OEM hardware, with all instructions provided. The control arms are made of 1.625" OD x 0.120" DOM Mild Steel Tubing, CNC machined for precision, and TIG and MIG welded for durability. They come with "On Car" greaseable Bushings with grease fittings and a long-lasting powder coat finish.
