It will be easier to install than a body lift. However, the Skyjacker lift hasn't received the greatest reviews. I know a couple of members here and at FTW have installed and removed them. They create some extreme angles on your suspension components. That must be why all of the other leveling kits limit their height to 2.5 inches. Also, You won't fit 35's on a 10 inch wheel on a 4x2 with only 3 inches of lift. I'd suggest a 3 inch body lift and one of the 2.5 inch leveling kits if you want to fit 35's on your 4x2 inexpensively.
