Great thread.Was not aware this could be done on the H3. I did this on my 03 blazer but instead of raising i lowered it down.

With the Hummer i get it up. Thanks

 

both new axles, boots are torn & had to replace a balljoint, might be a coincidence, but I can't understand why the boots would tear in less than 7 months of driving

 

Theres no after market or oem boots to just replace? The whole axel needs to be replace everytime correct?

 

To all new HUMMER H3/H3T owners.

If you stay at or below the recommended 23.5" measurement you should not have any issues with premature parts wear.

If you are concerned with premature parts wear, then you do not modify any of the suspension geometry.

 

So when leveling out the truck by just tightening the front torsion bars what shocks would you recommend for an oem type reaction when breaking? additionally, what size shock would y'all recommend?

 

I changed all oems for Bilsteins 5100 series, + 2" travel, happy since years with them

 

hey guys. new here. I have a question regarding cranking the T-bars. I have read a lot about it in several places and decided to just do it. My rear sits at 24 1/4" from center of wheel to fender. I cranked my T-bars to 23 1/2" from center of wheel to fender. So, yea i just leveled it, which is fine with me. I have read that 23 1/2" is ball park max on the front without too much wear on the drivetrain. However i keep reading where guys have added rear shackles to raise the rear 1 1/2 - 2 ". Now if I'm understanding correctly, that would put the rear that much higher than the front and one cannot crank the front any high without resulting in damage. Can someone please explain how guys are adding rear shackles and cranking the T-bars up enough to "level" the H3? Thanks

 

They are not "leveling" with the extended rear shackles. This would provide the same OEM forward rake and just raise the front and rear.

 

Ok. So if the max available height in the front is 23 1/2 from center of wheel to fender why set the rear at 26?
whats the advantage.

 

None. Except to make the rear look higher again.
