Cognito 11-19 Chevy/GMC Silverado/Sierra 2500/3500 HD 2WD/4WD 12in Perf Lift Kit w/ Fox PSRR 2.0

When you're ready to give your 2011-2019 Chevrolet Silverado or GMC Sierra 2500/3500 HD a serious height upgrade, this Cognito 12-inch Performance Lift Kit bundles everything you need. This kit is designed to lift the front of your truck by 12 inches and the rear by 5 inches, giving you the clearance for larger tires and a commanding stance. Cognito components are engineered, manufactured, and assembled right here in the USA, ensuring a well-built product you can trust.

At the heart of this kit are the Fox 2.0 Performance Series Remote Reservoir shocks. These shocks feature an extruded aluminum body for better cooling and are designed to prevent oil aeration, allowing the factory-tuned valving to perform at its best. You'll notice a more comfortable ride on the road and predictable handling when you venture off-road. The kit also includes Cognito's SM Series Upper Control Arms, which are boxed sheet metal arms that are CNC robot welded and powder coated. These arms correct the ball joint angle for lifted applications and include new crush sleeves and polyurethane bushings. For improved steering stability, the patented Cognito Pitman and Idler Arm Support Kit is included. This kit addresses a long-standing wear issue in GM truck steering systems by providing extra support to eliminate center-link movement. A 1.5-inch diameter HD front sway bar made from heat-treated 4140 chromoly steel is also part of the package, designed to reduce body roll and improve traction. Finally, the rear lift is achieved with a 5-inch steel block and U-bolt kit, and a 4-inch arched Deaver leaf pack made from high-quality spring steel with a higher leaf count for a compliant ride.

This comprehensive kit aims to correct CV joint angles for the front driveline, which is especially important for 4WD models operating above 20 mph. While the kit provides a substantial lift, it's designed to maintain adequate droop travel for a superior ride quality. It also includes extended stainless steel brake lines and forged torsion bar keys for the front suspension. With a DIY install time estimated at 17 hours, this kit offers a complete solution for achieving a significant lift and enhanced performance for your heavy-duty truck.
