Looking at the colorados they have a Driver side diff drop, from the pictures I've seen the driveshaft just barely squeezes through the cross-member(If I remember the name right) from my understanding the hummer's "crossmember" is wider, looking at pictures that is.

The 7.6 isn't exactly the strongest differential out there, I plan on doing a T-case swap if a driver side drop is possible here. I have read somewhere that removing the T-case in the h3 will cause the ABS and TCS to fail? I was hoping a 8.25" will fit, maybe even a 9.25" being able to fit a locker or LSD would be nice. I plan on pushing over 600hp. I could do a solid axle swap but I really do not want to cut up or weld the frame. This is a very ambitious idea which will certainly not work more than likely

 

H3s don’t need any lift kit to wheel with most anything.

You cannot mash the pedal with the wheels tuned in an H3 at just over 400HP. Causes super squirrelly things to happen. Put your 600 HP in a 2WD pickup and have a blast.

Good luck with your project.

 

I'm going to be honest with you, I'm a absolute mall crawler, my truck is way too precious to me to do any off-roading, and idk any off-roading spots remotely near nebraska. Its a weekend car for me. I already have a 2wd v8 colorado, and its probably the fastest thing I've ever owned but I like my hummer way better

 

I guess my real question is, does removing the OEM T-case cause any errors? I've read that it disables TCS and ABS but I'm not sure of these
