[5 speed dual range fulltime 4wd questions]

Fulltime w/difflock swap is exactly the same as regular EA 5spd d/r swap.  with the exception that you need to add switching solenoids in addition to the d/r lever hookup.  Easy, use Single range pushbutton solenoids and spdt switch.

It is possible to put the 1.59 reduction into the FT box.  Good chance to put the 23 spline stubs in the front diff, casue there isn't an easy option for 25 spline axles in the Brat (unless you got EA82 front)  

It is NOT possible (to my knowledge)  to swap the final drive to 3.9 or 4.11,  as there was never a correct pinion shaft in that ratio for the FT4wd box.

So you'd end up with tall first gear.  Funny thing is those boxes have LOWER ratio 2nd through 5th.  So it offsets the 3.7 ratio a little bit.

But can you swap 3.7 for the 3.9. I don't know nothing about the 4.11 in these

Agreed with FerGloyale. 

I believe there is the FT4wd box in 3.9 ratio but it’s a difficult one to find. 

If you want a better diff ratio the only way to do it is to customise the pinion shaft.  I’ve got 4.111:1 in mine and it works a treat. I do wish I put in the extra effort/coin and got 4.44:1 though. 

If you do got for a 4.xx ratio you’ll need to also shave the crown wheel to clear the larger L series low range gears. 

Mince you’re running one of these boxes there’s a coupe of “rules” to keep the centre diff happy:

1) always run tyres of the same make/model with the same pressure!

2) once on anything remotely loose/slippery LOCK THE DIFF!  This will reduce the possibility of one axle spinning faster than the other. Locking the diff in these situations will prolong the life of the diff (which is hard to find in good condition these days!).

How'd you get 4.11 gear, who done it and how much

el_freddo how'd you get 4.11 gears in it front and rear. And how much did it cost

Alright my transmission swapped brat guys. Looking to either get a 5 speed d/r or if I can find one 5 speed d/r fulltime 4wd with the center diff lock. But my question is what does it take to make the fulltime 4wd one work in my brat and can you swap the 3.9 into it and also the rear lsd and can you swap the 1.5 lo gear into one. Also if you have everything I need for sale for a swap post it too. Thanks
