Each Cognito billet control arm is precision-machined from high-quality 6061 aluminum and finished in durable black anodize, resulting in a lightweight yet highly durable component proving to be one of the strongest upper control arms we’ve developed to date. All required hardware and detailed step-by-step instructions are included for a smooth and hassle-free installation.               

Our Billet upper control arms are equipped with the Delta Pro ball joint, designed to deliver more strength than a traditional ball joint with the articulation benefits typically associated with a uniball. While uniballs are known for smooth articulation, they can be vulnerable to environmental exposure in daily driving conditions. Cognito’s design addresses this by incorporating a protective housing with Zinc corrosion-resistant plating and a durable grease seal to keep contaminants out.

The metal-on-metal construction and greaseable design promotes long-lasting performance of the Delta Joint while allowing noiseless operation. What makes the Delta Joint stand apart from the alternative is that it provides increased durability over standard uniballs while offering greater articulation than conventional ball joint. delivering a well-balanced solution for both on-road comfort and off-road capability.
