4" 2007-2018 GMC Sierra 1500 Performance Lift Kit (w/Fox 2.0 Coilovers & Shocks) by Cognito

This Cognito Motorsports 210-P0958 4-inch Performance Lift Kit for the GMC Sierra 1500 is an excellent upgrade to increase ride height to allow clearance for larger diameter tires (up to 33x12.5) while improving suspension performance in on- and off-road conditions.

This kit features Fox 2.0 Performance Series Coilovers and Shocks. The dampers will improve ride quality and perform great when you hit the trail. The Fox uses a 2-inch extruded aluminum body that minimizes internal heat, resists rust, and looks great. An internal IFP (internal floating piston) mono-tube design inside the shock body keeps the oil separate from the high-pressure nitro gas, resulting in a great ride on the road and superior off-road performance. 

Also included are custom-fabricated spindles (steering knuckles), all necessary installation brackets, and an integrated skid plate that securely connects the front and rear cross members, providing exceptional front-end rigidity. These components are proudly made in the USA and finished with a durable semi-gloss black powder coating.

The Cognito 2-Inch Block and U-Bolt Kit include 2-inch tall, powder-coated semi-gloss black cast steel blocks and heavy-duty zinc-plated U-bolts for a durable and secure lift

The Ball Joint SM Series Upper Control Arms enhance your vehicle's style, function, and performance by correcting the ball joint angle for lifted and leveled applications. This correction improves droop travel, resulting in better ride quality. The control arms are constructed from boxed sheet metal, welded, and finished with a semi-gloss black powder coating. The kit includes pre-installed, maintenance-free ball joints and pivot bushings.
