Collection: Cognito
Cognito Motorsports is a premier American manufacturer of heavy-duty suspension components and lift systems engineered for trucks that work as hard as they play. With decades of experience in racing and off-road fabrication, Cognito has built a reputation for producing some of the strongest, most reliable suspension upgrades on the market, using premium materials like billet aluminum, forged steel, and chromoly to ensure every part can withstand the abuse of towing, hauling, desert running, and trail conquering. At Stateside Performance, we stock a wide selection of Cognito products designed to transform your truck's stance, capability, and ride quality. Our Cognito lineup includes economy and standard leveling kits in multiple lift heights, ball joint upper control arm kits, forged pitman and idler arm support kits, tie rod upgrades, sway bar end links, traction bars, and complete long-travel suspension packages. Whether you're looking to clear larger tires, eliminate front-end sag, reinforce vulnerable steering components, or build a serious off-road rig, Cognito has the engineered solution. While Cognito specializes primarily in GM platforms, we offer fitment options across Ford, Chevy, GMC, Ram, Dodge, Jeep, and Cadillac trucks and SUVs, so drivers across every major American brand can find the right setup for their build. Each component is precision-machined in the USA and backed by Cognito's commitment to quality and performance.
