DSE Rear Tubular Sway Bar Kit - 1-1/8 Inch - 3 Inch Axle Tubes (042213DS) - 1978-1988 GM G-Body
Step up the rear roll control of your performance-focused GM G-Body with the Detroit Speed Rear Tubular Sway Bar Kit. Designed for 1978-1988 GM G-Body applications with 3 inch axle tubes, part number 042213DS uses a 1-1/8 inch tubular rear sway bar engineered for more competitive performance applications. With two available rate settings, this kit gives you the ability to tune rear roll stiffness and chassis balance to better match your suspension setup and driving demands.
Detroit Speed improves on the factory lower control arm-mounted sway bar arrangement by attaching the bar directly to the rear axle housing and chassis crossmember. This allows the chassis to stabilize the rear axle rather than transferring the load through the opposite control arm, helping minimize deflection under heavy cornering loads. Low-friction ball-style end links allow free articulation throughout rear suspension travel to help eliminate binding, while split lock collars positively locate the bar. The tubular steel sway bar is finished in high-gloss black powder coat and comes with the required mounting components for installation.
