I have heard good and bad about it. Some people say it is mostly a show lift, while others say with a little beefing up, its a great kit for off-road use.

 

Tuff trucks/trucking suspension the kit. I know of one shop in here in the Denver area that has installed 3 of the kits and refuses to do anymore. The kits are supposed to be direct bolt with no cutting or welding. They have had to do minor welding to make things stay together properly. The main issues are not holding alignments, bolt failure.
