No way. How is that even possible?

When you pull the lever into 4 high or low the tcase spins the front and rear outputs. How in the hell does some wiring prevent that from occurring.

Or does it prevent the CAD from engaging????

Prevents CAD yes. Honestly I've been sitting scratching my head for an hour trying to figure out why anyone would possible want to do this. Maybe someone has a reason but when you want the slow real low gearing usually you want to be locked up in full 4wd so..... This doesn't seem valuable to me unless you want to run 6th gear at 15mph
And if it's to get a truly massive weight moving well 2wd would be useless as you would just spin anyway so you want all 4 tires...... I just don't get it. For really slow tight turning?

Yeah. Like when i am moving my travel trailer around in the driveway. Or in a tight trail where you are using low range moreso for slow, fine movement rather than traction.

I have a g56. Just bought parts to do this on my own, now I have plug and play option. Awesome for backing up and spotting trailer without smoking clutch. Also awesome for cruising crap roads without binding everything up. Stoked for this. Makes sense for a MT truck

If you have a g56 i dont think this is going to work for you. Your front axle dosnt have a CAD does it?

A free spin kit would do the same thing if you don't have CAD, just costs more.

But it provides other benefits.

I had a land rover discovery that could do this. It was very handy for towing my 8000# boat on hills. Primarily to utilize braking though gear reduction and engine compression.

Is there a free spin kit for the cad trucks? I hadn't seen one yet. Manual trucks still get the cad.

I like 2 low for towing even with an auto.

Main thing on this truck, I would use it to unlock the sway bar on rough trails with good traction.

WHAT HUBS?
Not going to work on anything without cad yet they list 2009 and up. What a bunch of Maroons.

Did you have a kit on your D2? My D1 could lock and unlock 4 high and 4 low. As for 2 low the advantage is when you are on tight trails. You still have the low gearing but no bind when making tight turns.

I could certainly see where it would be handy for positioning trailers or towing heavy loads (like 2 grain wagons full, from the field to the farm, on the blacktop). Or hay wagons or equipment.

No. Read it again. 2500's are 14' and up. Damn MAROONS hahahaha.

The "hubs" part... yeah they effed up there. Should have said CAD.

They havnt offered a manual trans with a PW in years... and I am pretty sure it was back far enough before they had CAD too. Thats why I was saying I dont think it will work with his truck.

My mistake BUT I don't remember the 1500s of that vintage having the cad anymore either. It went away and stayed away for a long time on most mopar vehicles.

This. I can think of exactly the roads I would have loved to have this on back in Utah. I used to drive miles of rough, rocky roads, bone dry with great traction, limited to 10-15 mph by the lousy road conditions. Swaybar disco really smoothed the ride out, but 4WD was completely unnecessary.

Need to update my signature. I have a 2014 2500 g56. Lurk here as we want a lot of the same things.
I want a wagon but fuel range and towing at altitude pushed me to 6.7.

Yup. Perfect for the wagon owners. Aev was rumored to be looking at this. I bought a relay to do this on my own as it's super useful for what you describe.

My 47 and 58 Willys can do this.......

I used to feed cattle out of an old 50's International pickup. Would put in in 2wd low and hop in the back and scoop out the feed to the cattle. The old Binder would just crawl. Funny how things some of the first 4 wheel drive vehicles had and then disappeared are coming back again.

RustyPW · Post by **RustyPW** » Tue Jun 21, 2016 9:44 pm

I have the free spin hubs. And I've done the unlocked front hubs and stuck the transfer case in 4Lo and drove like that for a while at work. Came in handy.

TwinStick · Post by **TwinStick** » Tue Jun 21, 2016 10:28 pm

Not sure what you guys mean by disappeared & came back again. Manuals were avail for 2005-2008, w/Hemi, w/Power Wagon. I can still do that. 1st gear, Lo range, hop out & do what ever & hop back in. The advantage of having a 78:1 crawl ratio ! I would LOVE 2wd Lo range. For backing up my camper.

Manuals are STILL available but only with the CTD & the engine is de-tuned to around 610 lb ft of torque.

So you were just in 1st gear and in 4-Lo......

I was referencing the old 4 wheel drives that had two levers. One for 2wd/4wd and one for low/high range.

Nevermind......

What's the difference if you are in 4lo. So long as you are not on pavement.

I assume many want 2Lo specifically for use on pavement.

nts007 · Post by **nts007** » Thu Jun 23, 2016 2:16 pm

I'm still very unsure about this. I have never been in a situation where 4lo wouldn't work. If you truly need that much 2wd torque yore way over loaded. Like way way. If you need the pure traction and slow wheel speed then you use 4lo. I just can't see it being worth it. But that's my opinion. Can't think of any situation where 2lo would have ever been an advantage. Purely you would have little to no traction if your load requires that much power to move so you want the front wheel assist. Tho only think is a tighter turning radius. Just don't see value sry
