I purchased one of these with my 4 speed transfer case. I used it in my garage over a weekend and installed my new transfer case. This tool made the job so easy. if you have ever done something like this you know the standard lift get in your way. I had nothing in my way. This lift allowed me work freely under the jeep just the use of a creeper. Then with a simple turn of the jack i could use it to aline up everything to put my skid plate back after installation. If your doing your own install this is the one tool you really need. It will work on any vehicle. Best thing is if you are like me and your wife parks in the garage. You can just push it out for the night and then back in the garage in the morning.
