Control Arm

Browse New OEM control arms for GM vehicles. Our factory-original lower and upper control arm assemblies are sourced from GM surplus — correct bushing specification, ball joint geometry, and mounting bolt pattern for your specific suspension configuration.

Control arm geometry defines your vehicle's camber, caster, and toe characteristics. An OEM replacement arm maintains the factory-specified pickup point locations and bushing angles — ensuring a proper alignment result and factory handling after replacement.

Control arm replacement requires a four-wheel alignment after installation. Always replace control arm bushings when installing new arms. Verify part numbers against your vehicle's suspension option codes.
