Hummer H3 For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.

I'm thinking about leveling my H3

Quick check time, measure from center of the front wheel's hubcap to the fender lip. If its over 24" then it may be topped out. 23.5" is the sweet spot although mechanically you can go over 24 1/2 but the cv angles are pretty severe.

I have the oem fender flares on mine. I measured a few days ago and the fron was around 22'' and the rear was around 24'' rough estimates... I'll try to re-measure today.

With the flares you will have to make a non-standard measurement. How far from the ground to the bottom of the fender side marker lens?

I'm parked downhill so the weight on the front end has pushed my measurement down to 23.25" from center of hubcap to lip of fender. From the ground, the bottom of the side marker light is 38.0576825". Or just a hair over 38. Basically you should have 38.25", if less then you still have room for adjustment. 36.1 sounds like your front end is at stock height. Crawl under your truck and crank on the adjustment bolt (35mm??) until your front lifts to just under your target height, go to the other side and do the same and fine tune from there. Each side might take a different amount of turns to get there. Also, jacking up the front end makes it a lot easier to turn the adjusters. When done drive it a around the block a couple of times and re-measure to see how it has settled and then get an alignment when you have it where you want it.


Edit: I forgot to add that I'm on 35's, if yours are different adjust accordingly.

Gotcha. The place was a truck accesories place. Pretty big operation with four or five bays. They do lift kits and wheels and tires and stuff so you think they would know how to crank some torsion bars...

They had it up on a lift, but the lift was one of those drive up on it types... all four wheels were touching the lift...

I bet since there was pressure on it since the h3 was not supported by it's frame.. the guy tried to turn the bolt and it wouldn't budge.. so he came to the conclusion that they were already cranked all the way.. what do ya think?

I think that they don't know a thing about adjusting torsion bars.
Of course it's going to be tight with all wheels on the ground.

Have them read this - https://www.hummerforums.com/forum/h...ics-how-11428/

Or better yet, do it yourself. It's easy and only takes about 20 minutes to do.

Well I thing I am ging to try the lift/leveling soon. I guess I will need a pair of 2" lift shackles for the back, and craink the torsion bar in the front up to 2 1/2 inches if I am reading everything right.

That should give me a 3/4" lift in the back and 2 1/2" in the front. The only bad thing about this is I have to buy shocks also. And I guess Fox shocks are only for non lifted trucks.
I guess it will be front Bilstein with reserve 25176407 Shock Absorbers
and back Bilstein 24-185615 46mm Monotube Shock Absorbers

Unless someone knows better.....

I think you missed something.

You should adjust the T Bar bolts (no cranking involved) so the front is no more that 23.5" fender lip to hub center in the front, whether that is 2.5" higher than where your 3 is now depends upon your current measurement. You do not need any new shocks if you do not exceed 23.5", that is a misconception perpetuated by OLD information when people thought you co go up to 24" w/o issue.

You of course can get new shocks if you want to.
