The Cognito Elite 3" leveling kit for 2011–2019 Chevy/GMC Silverado and Sierra 2500/3500 (2WD/4WD) consolidates everything needed to lift and preserve ride dynamics. It pairs SM Series upper control arms with corrected ball joint angles, torsion bar keys, PISK pitman/idler support and King 2.5 reservoir shocks to maintain droop travel and improve drivability while allowing larger tires and a straightforward, mostly bolt-on installation.
