Benefits of a twin stick shifter Benefits of a twin stick shifter
Pros & Cons of a twin stick
Skiddy
07/18/06
Now why would anyone want to do something like that? Well because it has a very cool factor.

Pros: You can shift your front and rear independently
Pros: If you break your front or rear u-joint you can get home or
back to camp
Pros: If its snowy/icy and you have a locker in the rear you can
shift the rear into neutral and drive in front wheel drive, if
open differential a lot less squirrly
Pros: If you happen to get sideways on a hill or around an obstacle
you can shift the rear into neutral and just use front wheel
drive to pull you around
Pros: You can put both in neutral and no one will be able to figure
out how to steel it. Use your e-brake when doing this
Pros: Very simple to install on the J-shift transfer case
Pros: Will work with an auto or manual transmission
Pros: You can drive around in rear low two wheel drive, which
is fun when just poking along.
Pros: A lot easier to shift than the old single J shifter



Cons: You will have to widen your tunnel cover a little.
Cons: A little more difficult to install on a T-shift transfer case.
Cons: If your not careful you can mix up your hi and low and have a
real bucking Bronco



The shift pattern is: Left stick is for the front all the way back is Hi
Middle is Neutral
All the way forward is Low
Right stick is same, when normal driving you will want
your Left stick (front) in neutral and the right (rear) in
Hi

Here is what the shift rails will look like before and after you cut them this is for the J-shift T-case only.

Ken, one con that comes to mind immediately is that the twin sticks will pop outta gear, usually just when you need them the most. I use two boongie cords to keep mine in low range.
The pro is that it's much easier to shift the front end in and out on the fly. A full stop and the rear goes from low to high without any effort.

Normally that is caused by week detent springs and since it is easier to shift with twin sticks makes it seem that way.

If you go with the James Duff shifters you will also find that they are really shinny. Now how cool is that.

"j"

I have a "J" shifter box. I understand that there is a lot of discontent with this shifter but I can tell say this for sure. It's the fastest shifter for going from 2H to 4H or the reverse. If you keep it clean and lubed it does its job superbly! I can be traveling 50mph on a dirt road and slip it right into 4H! The reason many people have problems is the mismatch Ford put into the differential gear ratios. The 3.50 rear doesn't match with the 3.54 front and the 4.09 rear doesn't match the 4.11 front. This puts the transfer case in a bind. Sometimes it needs to be driven in reverse to get it out of 4L. That isn't a problem with the shifter but with Ford using the wrong gear sets!

I can do the same with my twin sticks, however after the J shifter gets older and worn they don't want to work as well.
The gear ratios don't match exactly because the front is a dana and rear is a ford 9". Also you always want your front just a little higher than the rear, I forgot the exact reasons but if you ask saddleup or others that are more experienced with gear mismached you can find why. Just my lil bit of .02, I know not much

FYI: Front and rear gears are mismatched deliberately to account for the different distance that the front and rear wheels travel when turning. The rears turn less than the front because they follow on a shorter arc. If the gears were the same they would really bind up.

By this logic then they would "really bind up" when going straight......
I'm not convinced.

T shifter

This is why I like the T verses having the J and wanting to go to a twin stick, however the twin does have its place but the guys that are just wanting it for 2 low the T already has it set for you and the gears are a little lower. 2 low is in between neutral an 4 low, try it you will feel it slip in and I run mine on the trail that way some times and don't seem to have any problems with it popping out.

You still cant have front wheel drive only with rear in reverse (a benefit of twin sticks).

They do build up. That is why you don't use 4 wheel on dry hard pavement and sometimes have to back up to shift back into high range.
I have been told when the ratio are the same you set up a gear noise then nothing then gear noise agine. I think the scouts has this problem. I never drove one though.

Does the twin sticks on a J box interfer with a hurst shifter on the 3 speed.
