Rim size
[QUOTE=h2offroad;322523]Over the almost 2 years Ive owned my h2, I've read probably every thread on every forum about hummer h2s.
99% of my research told me that 40s require a minimum of 6 inches of suspension lift.
I'm making this thread because I am successfully running and offroading 39.5" iroks on my hummer h2.
related mods include: 3" body lift, 2" wheel spacers.
that's it. Stock gearing, stock rims.
The v8 has plenty of power to turn these monsters and the transmission handles it perfectly. I do kinda baby it on the road, but offroad I beat the hell out of it. i have had 0 problems so far with tie rods an
whats is the rim size you're using for those Irocs?

Those are limited edition factory wheels iirc 17”
As an aside I remember when this was first posted, I hope OP eventually got 5.13 gears, he had to be running 900RPM at 60 in 4th with that setup, might as well be a 3 speed transmission because 4th was probably out of the question 90% of the time.
My truck struggles with 36”s with the 4.10s.

Good luck with this, I bought my H2 with 40's and 2 inch wheel spacers. It only had 41k miles on vehicle and the wheel bearings where destroyed. It has a 6 inch lift, but I went back to 38's and set of rims that I wouldnt require spacers. Most seem to like it considerably better. Ill try to attach pics later

Cant fit 40's
So, I tried to put 40x15.5's on my 03 H2 with a 2" body lift and it is not even close. There is a pretty large offset as well, as the 40's came off an H1. Now, I am looking for a good deal on a 6" lift kit. The kits are way more expensive for the H2's than the 25 or 3500 kits.

3" Body lift on H2 Hummer
Was a steering extension needed and anything else like brake line extensions to install the 3" body lift?

Those that say it's not possible are incorrect.
I would love to post pictures but my phone tells me my pictures are too large.
