The Tuff Country suspension lift kit uses extended steering knuckles and a three-piece sub frame that includes two cross members that are connected by a heavy duty skid plate. The skid plate will protect the front differential and will stabilize the cross members for strength and durability. 2” cast iron blocks will lift the rear and level your vehicle. To keep everything aligned, differential drop brackets and torsion bar drop brackets are used. This kit is easy and quicker to install.

Lift install was very easy instruct And pictures were very through. Lift performs very well no rust after one winter in Minnesota so far. Would recommend a 3in rear lift block if you are going to turn the lift all the way up for your truck to sit level. Used 1.75 in rear wheel spacer to make front and rear Tires stick out of the wheel well the same because the front gets about .75 to an 1in wider than stock when the lift is done. Overall great quality would definitely recommend.
