The Cognito 3in Premier Leveling Kit with Fox PSRR 2.0 shocks fits the 2015-2019 GMC Sierra 3500HD and delivers a bolt-on 3in front lift with race-proven damping.

Install Difficulty: Professional Install Only
Requires a vehicle lift, torsion bar unloading, upper control arm and steering component replacement; typically installs in 6-8 hours. Professional alignment required after installation.

Product Overview

This complete kit bundles Cognito SM Series upper control arms, torsion bar adjuster keys, the Cognito Pitman and Idler Arm Support Kit (PISK), front shock spacers, and Fox 2.0 Performance Series Remote Reservoir shocks front and rear.

The boxed sheet metal upper arms are welded and powder coated semi-gloss black, improving droop travel and ride quality on lifted trucks. The PISK adds support to the pitman and idler arms, eliminating center-link movement common on GM HD steering systems.

Fox 2.0 Remote Reservoir shocks add oil and nitrogen capacity for consistent damping over the roughest terrain. Engineered, manufactured, and assembled in the USA.
