Product Description

The QA1 52720 Street Lower Control Arm Kit offers a direct replacement for worn factory lower arms on classic GM rear-wheel-drive models. Designed with strong yet lightweight tubular steel and billet cross-shafts, the kit helps reduce unsprung mass and improve ride quality. QA1 Ultimate integrated ball joints minimize friction and wear, while black powder-coated surfaces resist corrosion.

Polyurethane bushings deliver precise suspension response while damping road noise - ideal for daily driving, street performance, or restored classics. Installation is bolt-in and straightforward. This kit also increases caster (~+2°) to enhance stability and handling. Compatible with QA1 Pro coil-over systems including single and double adjustable. Fitment confirmed through 1996; **2025 fitment unconfirmed**. This kit is for 2WD RWD GM F-Body, A-Body, X-Body, and B-Body vehicles only.
