Rear locker

Brochure shows different rear end ratio for manual trannys only. But research seems to indicate 4:56 rear end on all H3's. Fancy brochures by GM Marketing types with all kinds of CYA disclaimers are suspect.

At minimum you will need:
Electric locking diff case
Lockign diff side gear
Lock pin
Locking diff clutch spring
Locking diff ball bearing plate in board and outboard plates
Locking diff ball bearing assembly
Locking diff coil plate
Locking diff coil assembly
Diff carrier locking pins (eight or ten)
There is more too, and then there is the wiring, switch, new TCCM and of course a reprogram of the BCM/PCM, and maybe, just maybe (I'm not sure) you might even need a new BCM or PCM.

Just out of curiosity, I called the Hummer service department to ask about installing a locker on the H3? He explained to me until they come out with a factory Kit, the techs wouldn?t even attempt to install a locker because of the fear of something breaking later down the road and them being responsible. Also, he said he has not heard of any factory locker kit even coming out in the future for the H3? So like Bebee said to me.... 35 inch tires, and a good winch should do the trick...

You can replace the entire diff and axle.

Well after doing some more reseach in my parts catalog it wouldnt be feesable like most of you have pointed out. I guess I will just wait to see if an aftermarket kit becomes available or wait and get the locker when I trade this one in. The 35" tires are already on it and yes they help, but a locking rear makes alot of difference I never even realized how much until now that I dont have it.

Thanks Guys

Yep... I wished I would of purchase mine with the locker... Then I have a friend who just purchased the Toyota FJ with the locker and doesn't want to take it off-roading... Then here I sit wanting the damm thing knowing he'll never use his.... agggrrrr... The worst thing is that the sales person never said anything about the adventure model.... But, I should of did way more research.... So no one to blame but me...
