For 1978-'88 G-Body. These control arms are welded for maximum strength and visual impact. The lower control arms have a helical stamped coil spring mount which helps to secure the coil spring into the lower control arm. The coil mount was improved making installation quick n' efficient! The lower shock mount is mounted onto the stamped coil plate and accepts QA-1 & Ridetech Shockwave units. All arms that contain cross shafts are preassembled with the cross shafts and pivot sleeves and have a safety feature capturing both sides of the bushing. This helps to allow full control and provides no flex on the control arm when cornering. This kit comes with upper and lower control arms, ball joints, and D spec bushings.
