GMC Sierra 3500 HD Suspension Lift Kit – Cognito Premier 7" with Elka 2.5 RR Shocks (2020–2024). A USA-made, semi-gloss black system delivering a 7-inch front lift with precise damping control.

This kit corrects CV and ball-joint angles while preserving droop travel. SM Series Ball Joint Upper Control Arms are boxed, welded, and include maintenance-free joints and pivot bushings. The Cognito Pitman & Idler Arm Support Kit addresses steering wear by stabilizing the center link. Elka 2.5 remote-reservoir shocks with Dual Speed Compression adjusters improve control and comfort. Includes stainless steel extended brake lines, 5-inch rear blocks with heavy-duty zinc-plated U-bolts, and SM Series compression struts. A CV driveline is required if using 4WD above 20 mph.
