The Warn lift for my 86 CJ-7 did not come with shims, You may or may not need to get your driveshaft length changed,I did not have any problems with mine. The AT shock's are a little soft but seem too work well, I also have the Con-Ferr 3/8 longer shackles, I am installing a 1" body lift to help with the rubbing of my 32" 11.50's. If you do run in to drive shaft problems, I say spend the little extra to get it fixed with out using shims. just my .02. Good Luck with your project. Let us know how it goes.
