4'' Suspension lift questions!?!

I have my tj in the shop to put a Superlift Superride 4'' suspension on it. I also bought a SYE and extended driveshaft for it. The mechanic called and said 1. the back of the jeep sits lower than the front and 2. there is vibrations when you reach about 45-50 mph.

Any and all advice would be appreciated, Thanks again!!

Did you buy a CV driveshaft or just an extended non-CV driveshaft?

A CV shaft will require the pinion be tilted up to be inline with the driveshaft (as seen in the 1st pic here: Tom Wood's Custom Drive Shafts - Tom Woods Custom Drive Shafts Custom Driveshafts Specialist) in order to avoid vibes.

More info here: What is a CV shaft and why do I want one? - JeepForum.com
