im researching lifts and ive come across this 5" coil spring conversion from Pro Comp for my '90 Wrangler. it says that it will make my ride a lot smoother which would be great considering that ill be more on-road than off-road most likely. ive read reviews about it and they all say pretty good things about it and that it preforms just as well as any other lift. has anyone put this on or heard anything about it? thanks
