Cognito 2021-2026 Chevrolet Tahoe & Suburban/2021-2026 GMC Yukon & Yukon XL, 2.5-3.25 Inch Lift, SM UCA, w/ Cognito RR Coilovers

The Cognito 21-26 GM SUV Elite Level Kit is engineered to increase wheel travel, damping capability, and suspension performance for exceptional vehicle control and ride quality on and off the road. Adjustable front coilovers provide 2.5-3.25 Inch of lift, while adjustable rear coilovers provide 3-4 Inch, allowing fitment of larger and more aggressive tires. Cognito 2.5 Series coilovers feature vehicle-specific tuning, corrosion-resistant CAD-plated shock bodies, 7/8-inch shafts, and remote reservoirs that help maintain cooler operating temperatures during extended off-road use.

Fully rebuildable and re-tunable, the shocks can be serviced and customized as driving needs change. SM Series Upper Control Arms feature Cognito Alpha Joint ball joints for increased strength, durability, and high-angle articulation while providing an expanded alignment range and helping maintain proper suspension geometry at increased ride heights. FK rod-end bearings provide extended longevity and minimal deflection.

Fabricated Cognito GM SUV rear toe links help maintain proper rear-end alignment at taller ride heights, improving suspension geometry and reducing unwanted tire wear and handling characteristics. With up to a 20 percent increase in front wheel travel over stock, this Elite Level Kit delivers the suspension capability needed for improved performance, comfort, and control.
