Chevrolet Silverado 3500HD Suspension Lift Kit - Front + Rear - Cognito - 2.0 IFP - 2020–2025. This front and rear aluminum, rebuildable shock set is tuned to deliver comfortable road manners and confident control on GM HD platforms.

Proper-length front shocks maximize travel without binding tie rods, lower ball joints, or CV axles; they act as the droop limiter and add about 35% more down travel. The gas-charged IFP keeps nitrogen and oil separated to reduce aeration and maintain consistent damping. Hard-anodized aluminum bodies, end caps, and seal heads help manage heat and resist corrosion, while a vulcanized upper bar pin and bushing provide OEM-like mounting. Rear shocks are optimized for stock height up to 1 inch of lift, and the kit is intended for leveling setups using an aftermarket upper control arm.
