GMC Sierra 2500 Suspension Lift Kit - Cognito - Elite 4" w/ Elka 2.5 RR Shocks - semi-gloss black - 2011-2019. This complete system delivers 4 inches of front lift and 1 inch of rear lift while preserving geometry and ride quality.

Engineered around Cognito SM Series ball-joint upper control arms—boxed, welded, and powder coated semi-gloss black—the kit corrects ball-joint angle and maintains adequate droop travel. The patented Pitman and Idler Arm Support Kit limits center-link movement to address common steering wear. A 1-inch rear block with heavy-duty zinc-plated U-bolts balances the rear. Elka 2.5 Performance Series remote-reservoir shocks with Dual Speed Compression adjusters are tuned for this platform to deliver a smoother ride, predictable handling, and added control under load.
