Pros: Cheap, good quality, great customer service, clear instructions
Cons: swapping the front springs to the rear gives it a rough ride, shocks that come with the lift (rough country) are really rough
Comments: I chose this lift because 1) it was one of the cheapest, 2) it was the most recommended lift for a zj, 3) i heard that IRO's customer service is among the best.
All of these reasons met my highest expectations. It is an awesome kit from an awesome parts company that is always willing to help.
My experience after lifting was bad at first. My ride was, imo horrible. I got it aligned, and just after, it would get knocked out of alignment. I got a new SS and that helped. I was still getting DW. I got new control arms in the front and that fixed my dw issues. It also helped smooth out the ride in the front. I got a pair of Rubicon express springs instead of using the stock rear springs and that massively helped with ride.
My recommendation is 1) when you are installing the lift, check your control arm bushings. 2) Buy a pair of rear springs instead of using the front springs.
