Gear driven T-cases like Dana 300, Atlas, NP205 all have individual dogs/forks/ (2 rods sticking out of the T-case operate each)
stock they are both controlled by one stick
twin stick connects a shifter to each fork so both the front and rear output can be selected individually High, Neutral, or Low

So 2wd high: put front in neutral; rear in High

4x4 low: put both in Low

Digs front in Low rear in Neutral use cutting brakes or e-brake to stop the rears from turning


Chain Driven T-cases NP231 242 241etc in order to drive the front they connect the front to the rear output via a chain so you can not drive the front tires without the rear tires turning.
Toyota's have a kit to disconnect the rear drive shaft so you can run just the fronts.


T-cases have internal lockouts that prevent people from accidentally splitting the ratios front high rear low. You actually need to modify the lock in Dana 300 to get 2wd rear Low.

I remove the lock all together to be honest with you I never heard of anyone splitting the ratios before but since the competition does not allow you to disengage the rear axle which is considered a "dig" per their rules. I run the rear in low range and the front in high.
Fronts will be spinning 2.66 times faster than the rear looks like the fronts are pealing out and the rears are not turning.
Since I have spools front/rear I cannot do cutting brakes on just one rear wheel like the others do.

Like I tell everyone that says I'll blow up my T-case.
Use your own judgment. One guy said he was going to call Atlas I told him Atlas would say you're crazy.
I have 2 spares until I break on I'm going to keep doing it.
but it does work and works awesome.
If I ever get my videos onto my computer I can show you how it works.

I've asked around on JF but no one ever answers me. What is a twin stick? I'd imagine you get two sticks coming from the tcase instead of one but what does the other do, and why is it so much better?

So did that answer your question?

Twin stick is more of a competition thing so you can disengage the rear axle apply the brakes on just the rear tires via e-brake or CNC cutting brakes which is a hand operated brake master that plumbs into your brake lines and uses your existing brakes.

So you just use the front axle to drag the front end around, turn insanely sharp.

Trail riding you don't loose points backing up a million times.


You can also do rear digs use rear wheel drive lock the fronts up helps you slid the rear around since you cannot steer the rear it just works with gravity (down hill) works really well with 4 wheel steering.

Almost any T-case can do that, but 2wd low helps a lot.

[XJcrazy00]

That does actually help a lot. I've heard of 2wd low and heard of its advantages, and how most Tcases can be upgraded for it, but the idea of locking the rear brakes is pretty cool. It explains all the fancy shit I noticed on a jeep at the jeep rally in 08. He had one of those hand operated brake masters on the floor next to his seat, and I didn't understand what it was for. Now I get it, thanks a lot.

I'll see if I can dig up pics of the rig, I have like 200+ pics from that day so I'll see whats good.

I am running a Dana 20, lets say it cost $200

true twin stick capability (moded shift rails and built shifters): free
Tera low 3.15:1 :$615
Atlas 32 spline output: $450

Ok so you get the idea. I priced an Atlas 3.8 with a speedometer output is about 1000 bucks more, and longer. For another 1000 I can add a 203 crawl box to have a "4 speed" transfer case. I bought the whole 203 for 40 bucks. You can do similar things with a dana 300.

I like the route I went, altho an Atlas is a nice piece.

An atlas compared to a 231 with the tera kit, I would go with the Atlas, for the reasons people have already said. Worth it just for the twin sticks alone, I think they are one of the best mods to any 4wd

What case are you running? I never really thought that much about this, when I did the twin stick mod to my case, I ground the rails, instead of removing the interlocks. I figured something like this would break the intermediate gear pretty easily, but I never thought that much about it.

[customcreationsllc]

I just have a Dana 300 with super duper top secret internal parts.
Instead of grinding down the rails I just took the Pills out.

The way I looked at it the case is strong enough to spin just the fronts or rear why wouldn't it be strong enough to spin the front while the back is resiting by 2.66 times.
I don't feel like getting into the internal works by typing.

I actually like it better than normal digs, I can still drive climb hills etc works down hill too it is like have the brakes on in the rear. Normal digs are only on/off.
Some course I basically ran the whole thing it split ratios.
I believe once the big dogs see what I'm doing they will do it too.


I'll have to get the videos online so I can show you guys.

Will do you have any videos of me?

I also have another top secret project where I made a part for one of the NP chain driven cases so it can do full out RCrocs legal digs just by changing out the one part.
I haven't tested it yet I still have to put it together and install it in a jeep and see if it works.
Who is ready for full out digs in class 1?????????????

If it works my plan is to have them made and sell them.
Anyone interested?


Just because no one does it doesn't mean it cannot be done.

What is digs?

Is that what locks the rear brakes?

[customcreationsllc]

"Digs" or "burns" is used to describe the whole action of disengaging the rear axle applying the brakes to just the rear and using the front to "dig" or "burn" your way around a sharp turn.

You can also do reverse dig/burn by locking up the fronts and using just the rear mostly use when you have 4 wheel steering.

[blakdot]

cody maybe i missed this I quickly skimmed through the thread, but why isnt a dana 300 with a 4:1 an option? Its by far tougher than a 231, and cheaper than an Atlas.
