Re: 2 Inch Lift on H2.
I don;t know where you guys are getting 40's from....that would be retarded!! 37's on teh stock rims just fit and allow full flex. 38's with a 4" Rancho kit (more like a 6" kit) barely allow for 38's and still allow it flex up all the way.
With 38's or larger, you can forget about even turning all the way.

Re: 2 Inch Lift on H2.
i can tell you what we are thinking.....simple math.
if we can run 37's on stock rims with no lift. thus, if i lift my rig 3 inches, and keep the wheels the same, 40"s are definately doable.
especially when individuals are running 40"s with only a 2 inch body lift and they actually wheel it......obviously it can be done.

Have at it. I had a Rancho lifted H2 with 37 13.50's. Ther new owner is running 38's....and he is out of room to try and fit 40's. I have also seen a Fabtech lifted H2 in action with 38's (6" lift) and he had rubbing issues as well. THat's with a true 6" kit/ so to say 40's will work awith a 3", I don;t see how...even with adding a 2" body lift. I also wouldn;t consider running that tire on a stock rim. I think (not sure) 40's go to a 14.50 wide? I think that tire will pop off the bead easily being that wide with these narrow rims.
So I don;t see how 40's would even come close to fit... and be even close to functional. If you have the rear sensors for the factory airbags, you can kiss those goodbye as well. You would have to relocate those sensors from the wheelwell alltogether.
So I think your "simple math" is off. there is no way 40's will fit. But go ahead and prove me wrong. it would look bada$$ for sure, but with a tire that big, would be wortheless. "Obviously" it would be a worthless truck with that size tire.

I can't speak of the bodylift but I can tell you that with a fabtech 6" lift, 40's will not work.
My 38's fit perfectly, no trimming, no rubbing (would make the frame shiny but not bear into it so that you could feel it)
The problem with 38's and especially 40's even if you could fit them is the truck would run like crap. When I installed 38's, I was so dissapointed with the performance, I installed 4.56 gears.... that didn't work so I installed a supercharger.
That's why I did the torsion bar bit with 35's. Looks decent and not so power robbing, it makes the truck nasty to drive.

Re: 2 Inch Lift on H2.
I agree, the Truxxx kit is pissa, I hate listening to the "know it alls" that argue about everything...who don't have it. I have it, and would do it again on my next Hummer H2 aswell.

Re: 2 Inch Lift on H2.
I'd like to do a 2 to 3" lift in the front and a 1.5" lift in the back... But, wouldnt it make my 35" tires look small ??? I dont want to go any bigger than 35" because 1) performance is already taken a hit, 2) I dont want my gas mileage to take a hit when you go 37"...
I just want to get rid of the rake I have... So my plan was to do the green torsion keys, get Deaver springs for the rear that are 1.5" longer ( but keep the same spring rates from the factory so it wont affect the towing capacities), Do the Fab tech tie rods, FOX 2.5 Resevoir shocks all around ( I was given $1300 install price, is that a good deal ???), and do all the cognito suspension upgrades...
I know by the time I've spent my money on those upgrades that I've spent enough money for a kit but I dont want too much of a lift any ways... I just want the rake get rid of the rake and have better suspension and stronger components in the suspension...
Any thoughts on my plans would be great for all you suspension gurus out there....
p.s. anyone know the part number for our rear springs w/o the air shocks ???? Deaver is asking me for them soo they can refference it with the springs they're planning on selling to me ....

Re: 2 Inch Lift on H2.
I run the 2.5/3 F and 1.5R with stock tires and I think it looks fine. Just has more articualtion room in the wells.

$1300 for just labor to install these items is too much.
i had all that labor (except change springs) for $500 labor in san diego.
also get a tuner so you can get more power and pep out of the h2

Re: 2 Inch Lift on H2.
OK that's what the fox shocks 2.5's cost, so your getting free installation.
but shop around you might be able to get a better price on the fox's.
try downsouthmotorsports.com

Re: 2 Inch Lift on H2.
If you decide to get the keys and stuff, let me know. I just installed a Truxx kit in the front and a set of spacers (1.5") in the rear.
I'm getting rid of it because I'm going to install an actual lift kit.
Let me know if you're interestedl, my kit isn't even 2 weeks old.
Mark
PS. And no, it doesn't look stupid with 35's, that's what I've got on there now.
