Post subject:  SJ80 Transfer Case Swap

G 'day Guys
I am wanting to do a SJ70 transfer case swap into my SJ80, I have a SJ70 transfer case ready to go in.
My SJ70 Transfer Case has got the SJ70 mounts and it has its factory flanges.
I am enquiring in what needs to be done to get the transfer case to fit.

Could someone please give me a list of parts required to make the transfer fit.


Cheers :beer:

And a WT front driveshaft. The sj80 shaft is longer due to the transfer case being shorter between the outputs.

Thanks For the INFO
Also does a sj70 case change the gearing much?

Cheers

WT transfer gearing is 7% lower in low and high range. Not enough to justify the swap. 1.0 litre gearing is much better and basically makes low 1st feel a whole gear lower than stock, but it’s still nothing like having reduction gears.
