All-In-One Big Lift

Adding this HD 12-inch lift to your Sierra/Silverado is not for the faint of heart. Built to get you over, around, and through bigger obstacles, Cognito has balanced this 2500/3500 lift kit to give you a comprehensive bumper-to-bumper suspension upgrade.

• Fox 2.0 Performance Series RR Shocks - Built with the latest in shock technology, these remote reservoir shocks have expanded volume for more gas and fluid to keep your shocks cooler and energy dampening more consistent. With an extruded aluminum body and factory-tuned precision valving, they give you a full 12-inches of front-end lift that lets you run up to 40 x 13.5-Inch tires on a 10-inch wide wheel with 4.5-inch backspacing.


• Cognito Ball-Joint Series Upper Control Arms - These performance UCAs give you a broader range of motion that supports your lifted suspension through extended wheel travel over rougher terrain. Featuring box-welded metal arms and black powder coating, they are both strong and striking.


• Cognito Idler and Pitman Arm Support Kit - The Idler and Pitman arms on the 2500 and 3500 have been a weak point for years. Cognito’s support kit is engineered to address these insufficiencies and eliminate the forward and rearward movement of the center link, especially as your suspension geometry changes as you lift your truck.


• Deaver Rear Leaf Spring - Deaver makes high-performance springs, and these are no exception. Giving you 4 inches of lift over your OEM rear leaf spring’s height, they help support your rear end and reduce kick during tough wheeling. Built with additional, thinner springs, they are more resilient during compression and rebound.


• Cognito 5-Inch Block and U-bolt Kit - To complete the 9-inch rear lift that levels your truck, this block and U-bolt kit gives you a solid mount for your Deaver springs. This includes semi-gloss black powder-coated steel blocks with heavy-duty zinc-plated U-bolts.


• Also included to round out this full suspension system overhaul are SM series compression struts, forged torsion bar keys, and steel braided brake lines. A CV drive line will be required for speeds over 20mph during 4WD driving. The entire kit is made and assembled in the United States.
