Pro Comp's Nitro Kit for the Chevy/GM 2500 4WD/2WD is a quick and easy way to achieve lift, add larger wheels and tires up to 33 inches and eliminate the factory nose-down rake. The Level Lift Nitro Kit is also ideal when adding aftermarket accessories to the front of your truck like snow plows, heavy-duty bumpers and winches. Torsion Keys are precision-forged chromoly and are stronger than OEM cast parts. Larger CNC-machined adjuster bolt pockets are engineered for a snug fit on torsion bar for optimized performance. This gives you the clearance and ability to add wider wheels and tires up to 33" in diameter. Torsion keys come with a durable powder coat finish. Give your Chevy/GMC 2500 HD an aggressive off-road stance without tampering with the factory steering geometry, preserving handling and ride quality.

Pro Comp Suspension is the only suspension company with products that are tested under true driving conditions on outside roads, rather than simulated testing. Shop Pro Comp Suspension Now
