Price: $450.00
Pros: affordable, easy to install, complete bolt on, comes with adjustable front track bar kit, fast shipping.
Cons: extended front sway bar links are a little iffy.
Recommended? Yes

Comments: 3.5" benchmark kit. Front to rear spring swap. Very easy to install. Comes with the RC hydro shocks unless you choose to upgrade, which I'm wishing I had. Also comes with adjustable front track bar and new bracket that replaces your old ball joint type track bar, which is also very easy to install. You will need a front end alignment after installing this kit. All in all a very good, affordable lift package that will definitely make a huge difference. I was very happy with the end result.

Price: $400.00

Comments: I would highly recommend if you install the 3.5 F/R swap kit in a ZJ that you also purchase adjustable upper arms & adjustable front and rear track bars.
I eventually added 2" spacers and stainless brake hoses. Turned out very nice.

Price: $300.00

Cons: rides like a damn dump truck
Recommended? Yes

Comments: only issue i had / have is one shock (front) came with the incorrect threaded nut for the top shock mount other than that it wasnt too bad could possibly use some better instructions

Price: $450.00
Pros: Decent Price, good quality, easy install, Looks good and works good
Cons: If you don't get a rear trackbar, your rear swaybars may hit the coil spring causes a loud clunk... The instructions could be better... but I'm not complaining.
Recommended? Yes

Comments: I really like this lift. The quality of the stuff is very good, and IRO is very helpful if you have any questions. The lift is affordable and just a great kit if you looking to get 3-4 inches. I would recommend getting front and rear trackbars with the lift. My rear sway bar on the passenger side hit the rear coil spring causing a loud clunk until I got a new rear trackbar. Overall I would recommend this lift to anyone looking for an affordable, good quality 3-4 inch lift.

Price: $499.00
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
Recommended? Yes

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.

Comments: Like the lift.
Rides rough on the CA freeways.
Need to go into the wilderness...
Can't remember the price.

Price: $997.00
Recommended? Yes

Comments: It is a great lift but with the increased height and the control arms remaining the same my axle is tilted forward which causes the springs when flexed going over bumps to bow forward and they hit on the stock track bar bracket. just makes an annoying loud banging noise. but i have upgraded to bilsteins, jks quicker discos and a rear adjustable track bar which is why the higher than listed price.

Comments: Good kit for money. Ride is a little rough on street. Need to purchase a rear trackbar or bracket seperatly
