1" 2019-2026 GMC Sierra 1500 AT4 4WD Performance Leveling Kit (w/Elka 2.0 Coilovers & Shocks) by Cognito

The Cognito 210-P1140 1-inch Performance Ball Joint Leveling Kit for GMC Sierra AT4 offers everything you need to upgrade your truck’s suspension with high-quality components. Engineered, manufactured, and assembled in the USA, this kit delivers improved ride quality and handling with no guesswork.

This complete kit includes the Cognito Ball Joint SM Series Upper Control Arm Kit, Elka Coilover front shocks, and Elka rear shocks, as well as all necessary hardware. The Cognito Ball Joint SM Series Upper Control Arms enhance your vehicle's style and function by increasing droop travel, resulting in better ride quality. These arms are made from boxed sheet metal, CNC robot-welded and finished with a semi-gloss black powder coat for durability. Pre-installed press-in ball joints are secured with black anodized, laser-etched Cognito caps. The kit also includes new crush sleeves and polyurethane bushings to ensure smooth, reliable performance over time.

The Elka 2.0 Coilovers and Shocks feature 2-inch-diameter bodies of hard-anodized aluminum for cooler dampening. They use an Internal Floating Piston (IFP) design that helps reduce vibration and cabin noise, providing a smoother and quieter ride. Optimized damping characteristics ensure increased comfort in both on-road and off-road conditions, especially when handling rough terrain like washboard surfaces and square-edge impacts. The shocks also improve vehicle stability, reducing front-end dive during braking or cornering, and enhance rear-end control when towing or carrying heavy loads.
