Give your Chevy/GMC 2500HD or 3500HD the height, stance, and capability it deserves with the Zone Offroad 5" Torsion Bar Drop Lift Kit. This system provides proper suspension and steering geometry without sacrificing ride comfort — while creating room to run up to 35” tires for a bold off-road presence.
Engineered using high-strength crossmembers, CNC-machined steering knuckles, and a heavy-duty differential skid plate, this kit increases ground clearance and improves approach angles. The FOX 2.0 Adventure Series shocks enhance control and stability on- and off-road, delivering a smooth ride with true performance damping. If you want the right lift for your HD truck — build it the Zone Offroad way.
