GMC Sierra 3500 Control Arm Kit - Front - Cognito - Billet, Delta Pro Ball Joint - Black - 20–26. Precision CNC-machined billet upper control arms for 2020–2026 GM HD trucks, built for strength, adjustability, and dependable daily use.

Each arm is machined from high-quality 6061 aluminum and finished in durable black anodize. The Cognito Delta Pro ball joint delivers greater strength than a traditional ball joint with articulation benefits similar to a uniball, while a zinc-plated protective housing and a grease seal help keep contaminants out. Metal-on-metal, greaseable construction supports long service life and quiet operation. PTFE-lined 7/8 in. FK rod ends provide camber and caster adjustability, improving front suspension geometry and optimizing ball joint angles through the full range of travel. Fits Silverado/Sierra 2500/3500 2WD/4WD, including AT4X & ZR2. Includes hardware and step-by-step instructions.
