Cognito 11-19 Chevy/GMC Silv/Sierra 2500/3500 HD 2WD/4WD 12in Elite Lift Kit w/ Elka 2.5 RR Shocks

When you're looking to give your 2011-2019 Chevrolet Silverado or GMC Sierra 2500/3500 HD a serious height upgrade, this 12-inch Elite Lift Kit from Cognito bundles everything you need. This kit is designed to provide a substantial lift while also correcting suspension geometry for better on-road and off-road performance. You'll get Cognito's SM Series Upper Control Arms, which are built with boxed sheet metal and powder-coated semi-gloss black, featuring pre-installed, maintenance-free ball joints and pivot bushings. These arms help correct ball joint angles for lifted applications and improve droop travel for a smoother ride. The kit also includes Cognito's patented Pitman Idler Arm Support Kit, addressing a long-standing wear issue in GM truck steering systems by adding crucial support to eliminate unwanted movement.

The heart of this kit's performance comes from the Elka 2.5 Reservoir shocks. These shocks offer external reservoirs for increased oil volume, leading to cooler operating temperatures and more consistent damping. You can fine-tune both high- and low-speed compression damping to match your driving style and the terrain you're tackling. In the rear, you'll find a Deaver leaf pack, specifically arched for a 4-inch rear lift over stock, made from high-quality spring steel with a higher leaf count and thinner material for a more compliant ride. This is paired with Cognito's 5-inch Block and U-Bolt Kit, featuring powder-coated steel blocks and heavy-duty zinc-plated U-bolts, yielding a total of 9 inches of rear lift. Forged torsion bar keys and an HD front sway bar are also included to complete the front suspension setup.

This kit is engineered and manufactured in the USA, ensuring well-built components. It's designed to yield 12 inches of front lift and level the vehicle front to rear. For 4WD models, a CV front driveline is required if you plan on operating in 4WD above 20 mph. While installation is a DIY project with an estimated 19 hours, it's a complex job that requires careful attention to detail.
