If you guys start running front lockers you're gonna have to modify your "no breakage" rule for your trailrides.

Snap, crackle, pop...now that's good wheelin'!

Allen.....my man!!!!

Allen here finally made it out to one of our events. This guy saw fit to challenge the hardest, nastiest and loosest route up a nasty hill.....AND MADE IT!!!!!

I know exactly what your thinking when inquiring about a front locker. As soon as one if available I'm going to get one too!

Even my buddy with his H1 had to work to get up that hill. And he has huge-fat PJ dirt-grips aired down to about 12 pounds: big-time advantaage.

Allen ran that hill so hard that at one point the dust/dirt completely encompassed his rig and we couldn't even see it....but sure enough, he emerged atop the hill...victorious!

I suspect you weren't aired down much....your tires looked pretty firm and square....but you still made it!

Yeah. IIRC, there is an Eaton E-Locker (similar to what is in the H2's rear end) coming out for the front of the H2. Also, I believe ARB makes an air locker for the front of 3/4 ton GM trucks, which I'm pretty sure have the same front diff as the H2.

If you go to the tech forum and do a search, there's a pretty large thread on this very topic. I think it was Steve R who started it, back in Feb.

Allen:

I asked about this topic a few weeks ago. Eaton appears to be the only source that is developing a unit. As you know, the Traction Control currently takes the place of a Front Locker, so I'm not sure how a Front Locker might pair with the TC system on the H2.

I'd think that the TC would have to be overrided, since the front axle will be locked and there's no longer a requirement for the system to send torque to the wheel with less rotation (i.e. more grip)? I like the predictability of Lockers, compared to the Traction Control that can engage when it feels appropriate. The downside to Front Lockers is that the rig can drive a bit "jerkey" on harder surfaces like packed dirt [especially when turning].

I think the T/C and "traction on demand" are differnt animals. The T/C is by brake on each wheel, and so doesn't cut out when you lock the rear diff -it wouldn't matter at all if all 4 were locked, since none could spin faster than the others. It just wouldn't ever kick in.

I am disappointed that you can't turn off the T/C in regular 4X mode though...

Has anyone heard if there are front lockers being made available for the H2?

So if you let air out of your tires to off road, and you drove along way to get there, or you get stuck and let the air out of your tires, how do you get home on 12lbs of air on a highway where you would normally drive 70mph?

Allen,

Great pic....just shrink it down so we can all see it!

Don't ya hate the way pictures rob the true dimensions of a hill? That hill was soooo steep that you couldn't possibly walk up it...yet the picture depicts a mere incline. sucks huh?

Btw....you had turned on your TC2 and then later turned it off. TC is always "on" and can only be modified into a different variation by pressing TC2. You had mistakenly thought the TC2 button was a front-locker of sorts...eek!

The rear locker is actually activated by a ball and ramp via an electromagnet.

This in turn pushes locking pins that lock the spider gears together, making the two axles locked together.

A video of the operation is here:
