Upper Control Arms, Suits 2-3.5", 4" & 6" Lifts, Set of 2 suits Chev 1500 (19-26) / GMC 1500 (19-25) by BDS Suspension
Increase wheel travel by upgrading the stock OE upper control arms (UCA) on your 2019-2026 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.

BDS wheel positioning guidance
Meeting a backspacing limit does not guarantee wheel fitment. Check wheel diameter, tyre size, brake clearance, suspension and all kit-specific requirements.
Results are approximate. The calculation allows an additional 1 inch for the wheel's two rim flanges (approximately 0.5 inch each). Actual flange dimensions vary between wheels.
Understanding wheel measurements
What is wheel backspacing?
The distance from the wheel mounting surface to the outermost edge of the inner rim flange, measured in inches.
What is wheel offset?
The distance between the wheel mounting surface and the wheel centreline, measured in millimetres.
Why does wheel width matter?
Two wheels with the same backspacing but different widths will have different offsets.
Why does BDS specify backspacing?
It helps position the wheel relative to steering and suspension parts, but is only one part of confirming fitment.
