Bilstein B8 Upper Control Arm Kit for 2019-2026 Chevrolet Silverado & GMC Sierra 1500

Fits select 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 models, including 1500 LTD and 1500 Limited editions.

Bilstein B8 Control Arms are engineered as a direct-fit upgrade for factory upper control arms on lifted trucks. This kit addresses the common geometry issues associated with suspension lifts by correcting caster alignment to restore straight-line stability and steering feel. The optimized pivot angles allow for increased wheel travel while significantly reducing stress on the ball joints and bushings during articulation.

Constructed from high-strength 4130 chromoly steel, these arms feature a tubular design that provides additional clearance for larger springs and shocks. The assembly is finished in a durable black powder coat and utilizes greasable polyurethane bushings for a quiet ride with minimal maintenance. These arms are fully compatible with Bilstein shocks and coilover systems, and all wear components are replaceable to ensure long-term serviceability.
