The height difference between this rear axle assembly and the stock unit on a 4x4 wheel is only about an inch or an inch and 1/2. So if you are looking for a 3 inch lifter this is not the kit for you. This is a great $210 kit just for the shocks. My truck now drives much smoother over bumps. The extra things you get with it like longer travel torsion bars also very useful for front end measurement All in all you can't beat it for the money and quality. Don't forget to order the side shock piston dust boots as they are not included. They only cost about $6 each for Rough Country.
