Product Description

The Bilstein 51-322335 B8 upper control arm kit is a performance suspension upgrade designed for 2019-2025 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. These tubular chromoly steel control arms replace the factory front upper control arms to maintain proper caster alignment - especially on lifted vehicles - and improve wheel travel and suspension articulation. The increased pivot angles and sturdy construction help reduce stress on joints while enhancing straight-line stability and handling characteristics.

Built with greaseable polyurethane bushings and sealed ball joints, these arms offer smoother movement, reduced deflection, and easier maintenance compared to stock rubber bushings. The direct-fit design ensures a straightforward installation with all necessary hardware included. Finished in durable black powder coat, this B8 control arm kit provides long-term corrosion resistance and works well with compatible shocks or coilovers for enhanced on-road and off-road performance.
