Bilstein B8 4130 Chromoly Front Upper Control Arm Kit for 2007-2016 Silverado/Sierra 1500 (51-304669)

Fits select 2007-2016 Chevrolet Silverado 1500 and GMC Sierra 1500 models.

The Bilstein B8 Upper Control Arm kit (51-304669) is a direct-fit upgrade for factory upper control arms on GM 1500 trucks. These arms are specifically engineered to correct caster alignment for improved straight-line stability on vehicles with lifted suspensions. The improved pivot angles allow for increased wheel travel while reducing joint stress during suspension articulation.

Fabricated from heavy-duty 4130 chromoly steel, the tubular design offers superior strength and provides additional clearance for larger springs and shock bodies. The kit features greasable polyurethane bushings and heavy-duty ball joints for an ideal balance of ride quality, durability, and minimal maintenance. All components are serviceable and replaceable for long-term reliability.
