WOULD THE 4X4 TRANSMISSION BOLT UP TO MY TRUCK AND DIFFERENTIAL, OR WOULD I NEED TO GET A CUSTOM DRIVESHAFT BUILT?

I have an 89 Toyota pickup with the 22R(carb). I have a 4 speeed in it. I put a locker in the rear differential and 31's on it.

When I am in the sand the motor has a hard time. I end up winding 1st out to over 30 miles an hour!

I would love the gears on the 4 speed, if I had 100 more hps and could wind my engine out to 8000 rpms. -but I dont.

I am considering putting a 4x4 transmission. I think with the extra gears I would be able to muscle this truck through most anything.

Does anyone have any details to this?

 

You will have to do a lot of fabrication. New crossmember, shift point in the tunnel, new driveline, etc.

 

different rear end gears might be a cheaper solution

 

X2. You can't go very fast in 4wd low, maybe about like your 1st gear is now.
