ARB Locker up front

So I Installed a ARB Locker for the rear of my truck and regeared It to 4.11's. Now Its time to regear the front and get a locker up there as well. I use my truck for daily driving and Sled pulling with the occasional drag strip. I'm going with the ARB to keep things the same on the truck but wanted to hear a real world answer to driving In the snow. I've been told that If I leave the switch deactivated ( Unlocked ) and engage my dash mounted 4wheel high that the truck with basically run 3 wheel drive correct? So only one front wheel will be driven ( which ever one has the ring gear on It ) Is this statement true? 3 wheel drive In the snow will be more then enough to keep me on the road and not In the ditch If I was to lock the diff.
Anyone that actually has a ARB In their front 9.25 let me know your real world answer to this.

If your front ARB is de activated, and the back is on and you put your truck in 4 wheel drive it will act the exact same as it does now (an open diff) so pretty much which ever tire has the least amount of traction will spin (3 wheel drive) this is actually better for snow in some cases because if the road is sloped to one side you won't just slide off. Once you activate the front it will be true 4 wheel drive. All 4 wheels will spin at the same speed until something breaks ...

Is there a switch in the cab to lock it and unlock it??

Thats what I wanted to hear. I wasnt fully sure of how It would all work. 3 Wheels bein driven will be plenty to get me through the snow we get around In Cali. Only time the front will ever be locked will be when I pull the sled In the dirt.

I think the ARB locker in the front is the way to go. As others mentioned, you can choose not to use it and it will perform like an open diff. And, when you decide you need more traction, it will act like a fully locked diff. I would love to have ARB lockers front and rear in my truck, but just can't justify the expense with what little off road driving I actually do in my truck.

The ARB Set up's are simple. There is one switch for compressor and another switch for each air locker you have. If you have 2 lockers then you have 2 switches & they never have to be ran at the same time. So to answer your questions, yes you will be able to turn the locker on and off from inside the cab on the fly..
