Sierra 1500 2019-2026 GMC Billet Upper Control Arm Kit by Cognito

Cognito Motorsports 110-91399 billet aluminum upper control arm kit upgrades suspension geometry, strength, and adjustability on GMC Sierra 1500 trucks and GM SUVs. Engineered for improved performance both on and off-road, this system corrects ball joint angles and enhances overall suspension movement throughout the full range of travel.

Each control arm is precision-machined from high-quality 6061 aluminum and finished with a durable black anodized coating, creating a lightweight yet extremely strong component. The design incorporates FK 7/8" heim joints to provide added adjustability for camber and caster, allowing for more precise alignment and improved handling compared to factory components.

At the center of the system is the Cognito Delta Joint, combining the strength of a ball joint with the articulation benefits of a uniball. Unlike traditional uniballs that are exposed to the elements, this design features a protective housing with zinc plating and a greaseable seal to keep contaminants out. The result is a durable, quiet, and long-lasting joint that delivers increased articulation without sacrificing daily drivability.

Designed for reliability and ease of installation, this kit includes all required hardware and detailed instructions, making it a high-performance upgrade for drivers looking to improve suspension capability, alignment control, and long-term durability.
