GMC Sierra 2500 HD Suspension Lift Kit by Cognito, Premier 7" with Elka 2.5 RR Shocks, semi-gloss black, for 2020–2024. This complete system lifts the front 7" and pairs precision-reservoir shocks for confident control on and off road.

Engineered, manufactured, and assembled in the USA, this kit is built around Cognito SM Series Ball Joint Upper Control Arms to correct ball joint angle and maintain droop travel. The design targets superior ride quality with corrected CV angles, plus steering longevity with the Cognito Pitman and Idler Arm Support Kit. Elka 2.5 RR shocks with Dual Speed Compression adjustment tame washboard and square-edge hits, reduce cabin noise, and improve stability under braking, cornering, towing, and load.
