Increase wheel travel by upgrading the stock OE upper control arms (UCA) on your 2019-2024 Chevy Silverado or GMC Sierra 1500 to BDS performance. Specially designed for leveled and lifted applications, these arms are built from high-strength 1.5-inch OD x .120-wall steel tubing and feature an indexed ball joint cup to correct the ball joint positioning.
These UCAs can be used with BDS lift kits and other lift and leveling kits on the market. The frame mounting ends feature durometer-specific rubber bushings and premium quality ball joints for smooth, quiet operation, and superior durability compared to arms featuring uniballs, poly bushings or heims.
Control arms typically add 1-2 degrees caster above stock alignment specifications.
Ball joint used is 081203, use this for replacement purposes if a new ball joint is ever needed. Ball joint is directional and must be installed with the 'dot' facing either inward or outward on the vehicle, otherwise damage may occur.
The BDS121260 UCA will work for stock height vehicles. These BDS121260 UCA will work with most leveling kits, such as the 2" ZONE leveling kits and all 4" and 6" BDS kits, along with 4" Trail Boss or AT4 kits.
Use BDS121255 for Denali models (6" only).
Use a maximum of 5.5" BS wheel for tire clearance to the upper ball joint when used on 2-3.5" kits. Can be used on 4-6" BDS kits with 6.25" BS (Factory) Wheel.
