I'm looking at gears for the hummer but can't find any usefull info that tells me in noob language what kind of differential this POS has...

Anyone can help me or point me to a online store?

Thanks..

 

If it's an H2, it is the same as my Tahoe. An 8.6" I believe with a G80 locking differential. In fact, the whole drivetrain is the same as well as most under the skin.

If an H3, it shares the Trailblazer platform.

If it's an H1, I don't know, sorry.

 

The H2 has an 8 Lug so it think it is a 14 bolt out of a 3/4 ton

 

The H2 basically shares the same drivetrain as a 3/4 ton as said. It is a 9.5" 14 bolt rear i'm almost positive.

 

Like stated above, the H2 is based off of a 3/4 ton and shares it's drivetrain components. The H3 uses 1/2 ton components. When I changed my gears to 4.56's in my 1/2 ton, they were ordered as replacements for an H3.

 

You're right...my bad. I forgot the H2 was based off the 3/4 ton chassis instead of the 1/2 ton in my Tahoe.
