Fits select 2014-2019 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks.

The Bilstein B8 Upper Control Arm (UCA) kit provides a high-strength, direct-fit solution for GM 1500 trucks with lifted suspension systems. Engineered to correct caster alignment, these arms restore straight-line stability and improve overall handling dynamics. The tubular design is fabricated from 4130 chromoly steel, offering superior strength over OE components while providing additional clearance for larger springs and shock absorbers.

Each kit features heavy-duty ball joints and greasable polyurethane bushings, striking an ideal balance between ride quality and long-term durability. These arms are designed to increase wheel travel and reduce stress on suspension joints during articulation. The set is finished in a durable black powder coat for maximum corrosion resistance and is fully compatible with Bilstein shocks and coilover upgrades.
