Can you give us a rundown on the install? I just picked mine up yesterday after work. I have been searching for an install thread but, can't seem to find one.
You can look up any FJ Cruiser suspension install How-To guide it doesn't have to be IronMan specific, the basic design is all the same. I will share a couple tips though.
The rear shock body is so much larger than stock that the lower shock mount is offset so it doesn't contact the axle housing under articulation. I don't think you could actually get it mounted the wrong way but be aware of this as you are test fitting.
The rear shocks will not expand on their own like a gas charged shock and expanding them by hand is a pain. What I did was slide the lower shock mount over the post on the axle. Install the bottom washer, bushing and locating washer on the piston. Jack that side of the axle up far enough to get the top of the shock through the upper shock mount and get a washer and the top nut threaded on a couple turns. Then drop that side of the axle down and let the weight of the axle extend the shock. Then jack it back up far enough to get the top bushing, washer and nut in place.
Assuming you don't have any seized hardware like I did the fronts are equally easy. Disconnect your sway bar. Remove the brackets holding your brake line and ABS sensor wire so you don't damage either of them when the suspension droops. Remove the 3 top nuts on the coilover, remove the lower shock mount bolt. Pull the lower end of the shock out of the LCA mount and the whole thing should just drop out. Repeat the process in reverse, re-attach all of your brake line brackets and sway bar.
FYI - If you are installing the SPC/LightRacing UCA,s make sure you torque down that top ball joint nut before you take your test drive! I decided it would be easier to torque them down once on the vehicle and then promptly forgot. 100 meters into my test drive they slide all the way in. The FJ had so much front camber it looked like a stanced V-Dub! Ooops!
