Well currently the CJ7 has a mild setup. By mild I mean its not working well.
The motor pumps out into a Ford C6 auto box, with reduction being done by a NP205 case. The diffs are running 4.56 ratios as I didnt want to lose to much meat off the D44 crown wheel. All this adds up to a final ratio around the 21.99:1 which is crap by anyones terms.
So the new idea. Simple is buy a Atlas or Klune but very costly and wheres the fun in that.
Heres my theory, make a doubler. Get my hands on a NP203 box, split out the range selector section, grab a Stazworks adapter and in theory presto I have a 4:1 reduction with final output up to 44.87:1
Hey Jimmy, may sound silly but how about making your own transfer case, I thought about when I was off road racing, you don't need high range? don't need to disengage 4wd? then something like a chain driven single speed transfercase would be fairly simple to make, know anyone with a lathe?
Thats correct CJ6..... That will be low enough. As it stands, when you go to climb a flat face thats as big as the 42" rubber, it struggles a bit. Yes the auto gets hot, not too hot though, running twin coolers and going to get into cooling in more in this 2nd rebuild of the vehicle.
Thats a stazworks adapter, connecting a NP203 front to a NP205 full case.
Or this kit from Northwest Fab, more expensive but more complete.
