UMI Performance 78-88 GM G-Body Tubular Non-Adjustable Upper Control Arms

Rear control arms are an essential suspension upgrade for your GM vehicle. Stock control arms can lead to traction loss and poor handling due to bushing deflection and weak material. Our tubular control arms offer improved performance for both street and track use. The polyurethane bushings provide better ride quality and reduce traction loss. These control arms are a direct replacement to minimize wheel hop, enhance cornering, and improve track consistency. Installation is a simple one-hour bolt-on process using OEM hardware.

Additional Information
