GMC Sierra 3500HD Suspension Lift Kit - Front - Cognito - 3in Standard SM Series (2020–2025). A precision front leveling package that delivers a true 3 inches of lift while preserving geometry and ride.

This kit reuses the OEM front shocks with spacers to set the proper droop stop, then adds Cognito SM Series upper control arms with a corrected ball joint angle for added droop. Torsion bar adjuster keys let you set ride height, and a 1-inch rear block and U-bolt set is included for trucks with permanent bed weight to bring stance back toward stock. Cognito designs around droop travel, maintaining a minimum 3 inches for consistent control and reduced nose-down rake.
