When purchasing a GMC Sierra 1500HD lift kit don't trust your truck to anything less than a Tuff Country EZ-Ride Suspension lift kit. More than your average lift kit, all systems are engineered to give the highest quality & best value on the market.

Tuff Country EZ-Ride Suspension's new "Strong" GMC 1500HD lift kits use new extended steering knuckles and a three-piece sub frame that includes two cross members that are connected by a heavy duty skid plate.

This design also allows for an easier and quicker installation. 2" cast iron blocks lift the rear to level the GMC Sierra 2500HD.

Review Product
Great product
Shipping was very fast and very reasonable from suspension connection. Absolutely the best deal I could find. After I had a front end collision, I had to replace my old lift kit and I chose this tuff country lift. Seems to be a solid product for a good price. The instructions are good, but if your going to install this kit yourself, your going to want to have a good assortment of tools to make the job easy. The 8-10 hour installation is a bit underestimated once you add rust into the equation, and my truck is pretty dang clean underneath. Lubricant is your friend. There were some minor paint blemishes that I had to touch up with undercoat. I'm assuming they had the parts hanging in a booth. I've been driving on salted roads and the finish seems to be holding up nicely though. I bought the tuff country shocks with the kit and the ride quality is good. If your looking for a 4" lift, my opinion is this is the best bang for you buck.
