Skunk2?s Rear Lower Control Arms are direct replacements, maintain OEM suspension geometry, and are ideal for street and race applications. Each arm is forged from aircraft-quality 2024 billet aluminum, precision CNC-machined, and is more than 25 percent lighter than the OEM arms. Skunk2 Rear Lower Control Arms also feature adjustable anti-sway bar mounting holes for advanced suspension tuning and optimum balance. The low-deflection, polyurethane bushings act as bearings for quicker response and a more positive feel.
