GMC Sierra 3500HD Suspension Lift Kit – Front + Rear – Cognito 3in Elite Leveling Kit w/ Fox 2.5 Performance Elite, semi-gloss black, for 2020–2024 models. A complete, matched system to level the front and upgrade control and ride quality on 2WD/4WD trucks.

This bundle pairs Cognito’s SM Series boxed upper control arms with forged torsion bar adjuster keys to achieve a true 3-inch front level while correcting ball-joint angle and maintaining droop travel. The Pitman & Idler Arm Support Kit reduces center-link deflection for improved steering consistency. Front and rear Fox 2.5 Performance Elite reservoir shocks—derived from off-road race tech—add external compression adjusters so you can quickly tune for load, terrain, and comfort. Engineered and assembled in the USA with a durable semi-gloss black finish.
