My jeep fabricator dude suggested I switch to a shackle reversal on my '82 CJ7 which has a skyjacker 4" lift and 33"s. Looks like MORE makes the best one, is this right? How will it improve my ride (smoother, hold a line straighter or what?) What is involved in the extended front driveshaft yoke? Am I correct that the MORE kit doesn't lift the front end? Thanks.
