Just called him, he said he will call me back in an hour after he gets off work.
I can go find the before and after sheet with the measurements but all around you gain about 3inches at the belly rockers bumpers etc all over a t bar crank. Your front diff skidplate will be a tad lower now that your CVs are level again but with the wheeling I have done I still have end to be hung up on the front diff skidplate. The rancho is great IMO. I would probably never go back to stock...I felt there hasnt been too much testing on the kit before I bought it, well documented testing, so I did just that. Check out my threads and I have tons of info. I will say the rear springs suck balls. Dont buy em, IMO. Go with shackles, an add a leaf and I will ask bebe or speedy about the addition of the chevy truck leaf. From what I understand it will help handle weight better and give a tad more height too.
I have been on some tough trails with this kit and it has exceeded my standards. If you pair that kit up with some tomp lo pro mounts or shcwarrty mounts you can gain clearance in the rear which is the next hang up. You can even go to a spring shop and have them arch the springs for more lift. Whatever you do stay away from 11-12 leaf packs if you are spring under. They handle weight so well, ride nice and handle jumping very well but are hang ups in rocks. I ran a big pack and went spring over. Since I did the spring over I am even more happy with the kit. It flexs well and has even more rear end clearance and still rides nice.
With that said I have seen comments on the rancho kit flexing less then stock. Heres why in my opinion since running the kit.

I personally believe its better then stock and if you do a spring over its a kick ass setup! I know 4speed loved his rancho kit but only went SA due front end weaknesses. If you have any questions let me know.
I am still testing this setup out, in mud I have been happy, in rocks I think its kicks ass and even handles side slopes well due to the added trackwidth.
