It should work good off-road, it's only an issue if one wheel loses all traction, but riding the brakes a bit should get the wheel spinning again in theory.
As a disclaimer, I have no experience driving a torsional diff off-road.

Has to be better then the G80 so it's a possibility.
 
I torsen diff never actually locks, it's a limited slip. If you get one wheel in the air once the worm gears start spinning they are free to spin.

With that said, sand, dirt, asphalt, they can work excellent. Its only if you get one wheel on ice or one wheel in the air that it will slip. And in that situation like Issaam said you can get a little power to that wheel by applying the brake.

I think it could work great for your rig Ben.

I plan to use one in the front of my K5 eventually, I'd put one in the back but I'm afraid the transbrake will break it, so I'm going spool.

I'm surprised the g80 isn't working. In a 14b, really, in good condition, they're pretty hard to beat.
When they do grab, the harder it tries to spin it, the harder it grabs.

Unknown miles out of it, got it from the junkyard. It still has the factory brake pads on it so I suspect low miles, it's the only thing that wasn't rebuilt in the diff when I had it redone.
 
I have had my '01 14B do the same thing as what you experienced. I stood on it from stopped and I believe that the speed went up fast enough to engage the speed lock-out in the G80 before it locked up.
The Truetrac would be great, IME. I have driven one on everything, including ice with my '70 K10. My son has one behind his Duramax and wished that he had installed it earlier than he did.
 
You can get that one, the Eaton E locker?

The thing I don;t like about an e locker or a ARB, is they are basically a spool or an open diff. They are never like a detroit where it will still allow one wheel to go faster so it doesn't bind up. When I have driven spools they can bind up sometimes, that never happened with Detroits front and rear.

I don't know how they work internally but he said he just rides the brakes until it lock then he lets go of the brakes, as long as you are still applying gas it stays locked up, so it sounds like a really tight limited slip.
I haven't driven one yet but I was spotting for hom and I saw the results

A Trutrac is a Torsen diff, works like a set of worm gears. It's a limited slip, it never "locks".


Here is a quick summary from my perspective of the options Ben:


Open - An open diff can send all power to one wheel, but at more speed.

Limited Slip - Such as Eaton has to overcome clutch friction to slip, but when more power is applied it also creates more friction, at least until it slips.

A Trutrac is a Torsen style, the same limited slip effect, but uses worm gears instead of clutches, no additives needed in the oil. Worm gears are like screw gears, they drive very easy from one direction but not from the other.

All limited slips can slip if one wheel has very low traction.


A Detroit locker works like a ratchet, where the ring gear is the handle, and the axles are the socket. It allows either wheel to spin faster than the ring gear, but not both. It's actually locked all the time, it only "unlocks" the faster wheel. People call it an automatic locker, but its really more of an automatic unlocker. It has a ramp type piece to switch directions in reverse instead of the direction lever.

Then there is the spool, which is just one solid piece from end to end. Same thing is welded solid.

Then there is a selective, whether it be ARB (pneumatic), OX9(cable), E-locker(electromagnet), etc. All of them are either open or a spool. So they can get bound up like a spool when locked, but they work as open when unlocked.

You have seen my deta log off the Holley, you know how it gets treated and that was a Sunday cruise to church. :haha:
 
Here is the only rust it has in the truck, very little has holes in it, do I replace the pitted parts to or just wire wheel it down and prime and paint it?
