For a 3" or less lift, for sure use the WJ lower arms. The bigger oval bushings provide a super improvement in handling and no worries on tire rub at full lock turns. There is plenty of adjustment room to add additional factory shims at the rear of the arms. I used one additional factory 4mm shim on each side, p/n 52003976, and these brought the caster angle back to factory specs with my 3" lift. There's no need to mess with the uppers arms unless they are due for replacement. They usually are, so I did replace mine with new OEM units. Very easy to do and was verified w. my magnetic finder, then an alignment check by the local dealer.
thanks alot
