Ive heard alot about the drivelines on the 4" lift and 37's. I ran a search and came up with no more information. so heres my question. has anyone running a 4" lift on a 2d wrangler had any driveline vibes or problems? If so were did you find new driveshafts to correct this problem? im sorry if a missed a thread. but im gettin down to the wire on which lift to order and im tryin to decide on a superlift 4" or rusty's 3.25". thanks

 

BUMP

id like to know as well

 

mines a 2dr with a 4" lift on 37's and im ok all the way around

 

I am in the same boat, I have decided to go with the Rusty's 3.25 so I can upgrade the componets of the kit as I go along, and add a 1" bl when I am ready to jump up to 37's. For now, it will be my dd, so it will be awhile before I run 37's.
