Rear locker

[springer]

Ok I have the base model and not having a rear locker sucks this is the first 4wd vehicle I have ever owned that doesnt have a locking rear diff. I work at a GM store in parts, but we are not a hummer dealer. I need some of you guys help trying to figure out what all is needed for me to put a rear locker in. In my parts catalog I found an e-locker kit which consist of the locking mechanism and a couple of other components and then the switch not sure what else I will need. Also it looks like the switch is in the dash with the 4wd selector switches, but I cant figure out where it would go. I am also not sure about the wiring. I might just need to wait for an aftermarket kit just thought some of you guys might have an idea.

Thanks
Tanner

So why the hell didn't you buy the adventure package?

We had only one hummer on our lot it had been sitting for almost 3 months and they needed to get rid of it so I got a deal on it. Also at the time I bought it I was under the impression that they all had locking rear diffs. Since on the 4wd switch there is a damn picture of a lock on the button IMO its stupid to even make a Hummer that doesnt have a locker. Is that enough explination for ya

If you add a rear locker you are probably going to want 33" tires.

With 33" tires you would want or wish you had 4.56:1 axle ratios like the Adventure Package

So think about the cost of:

New ring and pinion gears front and rear

Rear Locker and all switches and wiring etc

I thought the base H3 already came with 4.56 axles

according to this site, 4.56 axles are standard. Good thing too, cause that's an expensive upgrade.
