Ironman 4x4 Nitro Stage 2 Lift

[Run Forrest Run]

I just installed this kit but with the foam cells as Nitro we’re out of stock as were the top plates so I had to build the CO myself. Did you adjust the coilover at all or go with the 8.5” they come with pre-assembled. Mine is tall, which I like, but has a lot of bounce. I’m thinking I adjusted too high and will need to back them down.

Nitros are not adjustable so I’m at stock Ironman height. I did have them add a 5mm spacer on drivers side (sits below the coil) to compensate for drivers side lean, which added .4” to my after settled results below:
DF 22.5” +3” (Includes 5mm spacer)
PF 22.625” +2.75”
DR 24” +2.5”
PR 24” +2.25”

I used performance “B” springs, which did you go with?

I too went with the performance springs. I just talked to them and on the coilover, they label it as OEM but it has a 2.5” lift already dialed in so when I added some height on the coil it put them too high. I’m going to back them down to the 8.5 and see what that will do.

Hey Fishin check out this thread, it is specifically for the Foam Cell Pro's.

I assembled mine at 8.5" on the passenger side and 8.75" on the riverside. Came out 3" of lift with Performance Springs.

60 Day check in:

I’ve been chasing down a low speed ‘squeak’ for weeks. Checked all installation points, etc. Eventually found my alignment tech had only torqued lower control arms down to @ 40-50lbs vs factory 129 Ft lb Spec... After a re-alignment and proper torque, I’m back in spec with zero squeaks!

Over all, I’m extremely satisfied with the Nitro stage 2 kit. The ride is so sporty and solid around high speed turns and at highway speeds. The performance is great plus the stance is perfect to my eye. I’ve yet to go hard off road, but that’s not really my thing at this point either.

Thanks for the update! I've been following your post..

Have you done any off-roading with the new suspension yet? Any rubbing on the body mount?

I ordered a Stage 2 Pro and am wondering if I need to do the body mount chop. I'll be running 285.70/17's on a set of SCS Ray 10's 8.5"

Nothing more than forrest service roads so far, but I went with this kit because I don’t hard core off-road. Zero rubbing since the trimming, but haven’t come close to stuffing the tires. From talking to Ironman reps and reading other posts, I feel pretty safe without the BMC. That said, I have a grinder and a MIG, so not against it if need be- seems pretty simple. I’m running OE wheels, so your offset may have some effect. Post pics when you are done.

Thanks! - Will-do with the photos.

I'm good doing the BMC also - just wondering if I should do the circumcision while I have everything disassembled.

Got our Ironman stage 3 kit installed and are really impressed! Also installed 275 KO2's, really loving this setup.

Glad to hear- Share photos when you get a chance. To help others:
You went with the Nitro kit, correct?
Which springs did you use?
Did you add any spacers?
Any before/after measurements or actual lift numbers?

I went with Nitro shocks and have no regrets. Talked to Chris Wagner @ Ironman and after we talked he actually suggested Nitros for my use. I went with Medium springs front and rear as we will be adding a bumper and winch on the front and we tow a Smittybilt Scout trailer with it also. I didn't use spacers nor did I get before and after measurements wish I had now.

Looks great! I went with Medium springs with little extra weight (sliders, some recovery gear & tools). The ride is great unloaded and gives a little extra height for towing. I’m thinking about a hidden winch. Let me know if you see any measurable drop with extra weight up front.

September update: 2.5 months in & ride continues to feel planted, stable and sporty.
Took measurements and confirmed no additional settling.
Washed her up and took a few pics from different angles. Perhaps will help someone down the road know what to expect with this lift.

Looks great! Loving the stance.

Did you have any errors after doing the install? I just did the same install and am getting the VSC error. Did you have any similar issues?

Fortunately, no VSC issues here after lift.

@Run_Forrest_Run - Great looking setup. I'm interested in the Ironman Nitro setup as well but was a little worried about the stiff spring rates at 669lbs/in and 280lbs/in. Can you say how much firmer than stock they feel to you? Are you carrying anything in the rear?

I carry @100 lbs of tools and towing equipment.
The ride is a world of difference. It went from driving like a station wagon to driving like a proper 4x4. It’s not too stiff in my opinion, just very stable. Not harsh, but firm. If I did it again, I might go with the A springs for rear. I like the rake, but would be perfect if it was 1/2” lower in back. That said, I’m very happy with the result. I would not spend any more to replace rear springs. Hope this helps- Good luck!

Your thread has been super helpful and I've just bought a nitro kit for my 07. I got the 1.5" A rated rear coils since I don't have any bumpers, RTT, etc. I was also worried about the 8xx lb front performance spring but found the FJ coils have much lower spring rates. You have the B FJ coil at 660 lb so how do you like that up front? When you hit speed bumps or pot holes how would you describe the car reacts to it? I'm debating the A or B FJ coil up front and since the 4th gens are a little lighter than the 5th I'm leaning towards the A. Thanks for all your pics and write ups!

Congrats! I like my ride, can’t imagine 8xx lb coils... When I hit bumps, it’s firm vs getting soaked up. I’m sure the shock plays a part. The rear feels firmer than the front over speed bumps. Sounds like you will be happy with A’s in the rear. For your front coils, I suggest you choose A for comfort, B for little higher lift if you’re good with firmer feel. Hope this helps.
