Re: Engage Rear Locker in 4-Hi on H2?
Actually locked up is worse in the snow, tends to want to fishtail. My jeep is full time locked in the rear and tough to keep straight when in snow

Re: Engage Rear Locker in 4-Hi on H2?
Thanks for the heads up in the snow. In my Rubicon it was helpful in the sand in 4-Hi.

You haven't lived untill you went down a hill on pavement at 50 mph in the snow or ice with a locked diff .

Re: Engage Rear Locker in 4-Hi on H2?
Just because I live in Phoenix doe's not mean I don't drive in snow country . I grew up and lived in northern New Jersey (Susex and Morris county ),and hunt in Northern Arizona and Colorado every year. I also spent 2 years in Bufalo New York . and have a set of chains for the H2,and my 05 Chevy 2500 HD ext cab 4x4 Duramax/allison pickup. I drive in the snow and ice every winter .

Re: Engage Rear Locker in 4-Hi on H2?
I know it is possible to bypass the low range lock out so you can use the locker in 4 high on Jeeps so it must be doable on Hummers too??

Re: Engage Rear Locker in 4-Hi on H2?
I asked this question a while back and got the same responses. My brother in law did it on his TRD tacoma.....it's called a "grey wire mod" on their forums....apparently you just have to fool the locker into thinking it is "grounded" all the time.
Can someone confirm that this has been done on an H2?
DUCK

It will also cause the front end to shove badly at low speeds while turning.
