with 4.5" of lift it will help with the ride. I dont understand your comment about it not being as safe.
James @ares fab who is supplying all the armor for my build runs this set up as well as a good amount of folks that he wheels with and I have seen mixed reviews on it some good some bad. It is hard to wade through the opinions of folks who have never ran these systems I just do not think this set up is as safe as say this set up http://www.seriousoffroadproducts.c...01-XJ-Upgrade-Kit-For-Existing-4-7.5-S-A-Lift. due to the iron rock only useing a lower on the pass side vs upper and lower on pass side like the serious system.
