Ironman 4x4 Nitro Stage 2 Lift

[Run Forrest Run]

November, 5 month update:
Checked measurements last week with Ironman performance B springs and found the front settled (-.25”) to 2.75”. Rear was still holding at 2.5”. The large OEM rake was just not quite right to my eye..... So... Black Friday deals brought me a set of RRW RR2-V wheels and OME 2895E rear spring replacements. OME’s dropped rear down to a 2” lift.
Now sitting at 2.75” in the front with IM & 2” in the rear with OME. Visually still have a slight rake & much better balance to my eye.
Got out on some BLM roads on a day hike and very happy with the result.

Looks good. I just installed my IM lift but haven't taken pics yet. The front seems higher than I anticipated. I went with the TOYO55B up front and TOYO56A in the rear.

Like you, I've been reading and researching for months. I've gone full nerd and have a spreadsheet with spring rates from OME, Ironman, and Dobinsons.

One thing that stood out is the Ironman front coils are a lot higher rate than others. I'm wondering how that translates into ride quality..? I'm not sure how their dampers deal with the higher rates. It appears the OME philosophy is to use the same rate and make the spring longer for the most part.

I had been looking at the 65ABC front coils, but they may be too high of a rate. Might have to plot the 55s to see how they fall.

The more I get into it the more confusing it gets.

Most of us stick with A or B Front and Rear. Would be good to get your measurements before and after lift from center hub to wheel well. Hindsight, I would have tried A in the rear but I ended up changing to OME 895E due to overwhelming lift height info available on those.

I know your type... analysis paralysis...
I’m very happy with IM, just wanted slightly less rake with rear OMEs. Good luck, but remember all of the thinking and coil rate spreadsheet specs are splitting hairs over fractions of inches. Whatever you choose, you will be much happier compared to OEM ride.

Yeah, I currently have OME with 885 and 889. That was a decent set up before I added like 500# of steal and junk. It’s sagged to probably a 1.5”-2” lift by now. I could just update the springs but I have 50k on everything so might as well do everything.

Found a local off road shop that dialed in my alignment this week- Caster is now at 4* and all else is in spec.

Installed BFG KO2 285/70R17 in load range C. Had some rubbing at full lock on incline, so removed front mud flap, pushed front fender liner forward and trimmed the bumper. Was a little nervous to do this...after some reading, was a simple job. Well worth the work to fit these tires. Clearance looks good now and the stance is exactly what I was wanting. Will report back after some more miles.

Looks Really NICE! Any concerns with the KDSS on the install of this?

I’m no help to you on KDSS lifts. I’ve read enough to know there are limits.

I just ordered the Ironman nitro stage 2 with performance springs 2.5/2 based on your feedback. Very excited to get it installed.

I’m on the fence right now especially with Ironman’s 25% off Labor Day sale. I currently have 5100s and Dobinson springs for a front 2” and rear 1” lift.
I know you said the ironmans felt stable and planted... I get this weird “floaty” or light as a feather feeling when driving over 60mph on pavement with my current setup (much worse at stock, felt that starting at 25mph).
Regardless whether upgrading fixes that feeling for me, do you think these will perform better than the bilsteins/Dobinson setup I have with regards to everything else?

How are your cv angles? Have the iron man lift and I’m at 23” hub to fender. Was thinking to lower it about an inch because my initial measurements are close to yours.

I have this kit on the way. Did any of you get the drop differential after installing this kit?
