IRO 5.5 inch kit

dose anyone have the iron rock off road 5.5 fixed long arm kit? i didnt see any reviews on this paticular kit and was wondering if this kit was worth buying ? i will be coming into some money here in october and was wondering what will give me the best bang for my buck, and so far this kit looks superb. will i run into any problems with this kit ? it also says something about a trans 4 hole or 2 hole mount how will i know witch one to get? i have a 98 5.9 limited

I am running the IRO long arms and the belly skid and I would do it again in a heart beat. The arms are pure beef, even coming down on rocks didn't phase them. The install is very straight forward and even someone who hasnt lifted a ZJ before can do it easily in a weekend. The 4 hole or 2 hole is for the transmission mount. You most likely has a 4 hole, but you can check by looking on the underside of the crossmember and you will see either 2 or 4 bolts below the trans mount.

Upgrade to the Bilstien shocks and JKS disconnects.

I've been running this kit for about a month and LOVE it. With doetsch tech shocks it rides amazing. I have fixed la in front with fixed sa in rear. I do have a minor driveline vibe in the rear and will prob swap in adj rear uppers soon. Flex is amazing and highway driving up to 75 is very smooth. Well worth the investment....plus that iron y is just bada**. Took myself and two buddies approx 11 hours to do and that includes trying to source a piece of brakeline that got snapped at 8 on a sunday night...

You dont have to upgrade. I am running the stock steering with no issues.

You can upgrade to the IRO or Currie OTK systems.

As for problems, I only had the exhaust rattle against the subframe for the longarms, its a pretty easy fix requiring a cut on the hanger and re-welding.
