I have had nothing but great luck with all the USA Standard Gear products I have used over the years. I did not know enough or research enough the kits I was purchasing here. Waited 3 or so months after purchase to make other upgrades before doing install. Rear went fine front no so much. This kit is for Dana 30 HP reverse cut gears. Mine like most other 01 XJs is Dana 30 LP standard rotation. Had to order a different brand kit for front to get it done asap after tearing down. Because of time lapse when I purchased and when I fount out it was wrong kit I could no longer return wrong kit. Live and Learn

I ordered this kit for my 93 jeep xj. Dana 30 front 8.25 rear. The packaging was great. All of the parts are very well packaged and secure. BUT what I got was not what the photo shows. The kit I received is a non crush sleeve master kit. So now I need to track down a crush sleeve.
