Product Information

Get you new GMC Sierra 3500HD in the air with a suspension lift kit from Tuff Country EZ-Ride Suspension. This high quality 6" lift kit gives you enough fender well clearance to fit up to 35 inch tires. Once installed this kit will give your Silverado a great new aggressive look.

Extended steering knuckles and a mult-peice sub frame are the foundation of this GMC Sierra 3500HD lift kit. The steering knuckles keep the vehicle in alignment with needing to drop the upper control arms. The three-piece sub frame (two cross members and a heavy duty skid plate) make installation make easier than when installing a 1 piece sub frame kit. Also included in this is a torsion bar crossmember skid plate for added protection on your undercarriage. Differential drop brackets and torsion bar drop brackets keep everything in alignment. All front bump stop are relocated to maintain their factory specs. The rear of the vehicle is lifted using 4 inch (used to level the GMC Sierra 3500HD) cast iron lift blocks and extended ubolts.
