Cognito 3-Inch Premier Leveling Kit with Cognito 2.0 Remote Reservoir Shocks for 11-19 Silverado/Sierra 2500/3500 2WD/4WD

Upgrade your Silverado/Sierra 2500/3500 with a complete leveling solution engineered for performance, durability, and straightforward installation. Designed for both 2WD and 4WD models, this all-in-one package eliminates the guesswork by including the premium components needed to properly level your truck while improving ride quality, handling, and steering performance.

This Cognito leveling kit includes Cognito SM Series Upper Control Arms, the Cognito Pitman and Idler Arm Support Kit (PISK), Cognito 2.0 Remote Reservoir Aluminum shocks, and Torsion Bar Adjuster Keys.

The Cognito SM Series Upper Control Arms are designed to provide improved performance, style, and function for stock, leveled, and lifted applications. Constructed from heavy-duty boxed sheet metal and finished in a durable semi-gloss black powder coat, these arms feature corrected ball joint angles for leveled and lifted trucks while allowing increased droop travel for improved ride quality and suspension performance. Each arm is equipped with Cognito Alpha Joints and maintenance-free pivot bushings.

To further enhance steering system reliability, the included Cognito Pitman and Idler Arm Support Kit addresses common weaknesses found in factory GM steering systems. Cognito’s patented design adds critical support to the pitman and idler arms, significantly reducing unwanted center-link movement and improving steering precision, stability, and component longevity.

This kit is paired with Cognito 2.0 Remote Reservoir Aluminum shocks, engineered specifically for GM HD trucks to deliver exceptional ride quality, control, and durability in a direct bolt-on package. The external reservoirs increase oil capacity and improve heat dissipation to help maintain consistent damping performance under demanding conditions while adding a clean, aggressive appearance.

Featuring application-specific valving, rebuildable construction, and hard-anodized aluminum components, these shocks deliver predictable handling, improved ride quality, and confident control on and off road. Engineered to maximize suspension travel without binding critical suspension components, they help create a balanced suspension system built to handle the demands of daily driving, towing, work, and adventure.
