Anyone have any good contacts for a good Hummer shop to install upgrades as well as repairs needed? TIA!

 

Welcome to HF.

Nothing super secret or special about working on an H3. Anyone that can work on a GM truck can do it. Find a reputable local repair shop.

Personally, I do everything myself and I am nowhere near TX.

Best of luck.

 

Contact Mark at Mod Mafia. I know they are big into H1s. Not sure what all they work on outside of that.

 

The H3 is in common with both the GMC Canyon and Chevy Colorado. So most items aside from the reinforced frame and some other options. There are many of these units out there.

You will have no problems with any qualified shop being able to help with most issues.

 

As @Doc Olds mentioned, it’s a easy go on H3’s as far upgrades.
Keeping it maintained Houston has plenty of good shops.
Contact on FB the (chat page) Houston area off-road recovery chat group.
Plenty of ppl with reliable info for you.
