That is what I'm told and that appears to be the case when comparing part numbers. The idler and low speed gear are all that need changing and your low range would go from 1.92 to 2.28 or something like that. Not a huge change but every little bit helps.So are you guys saying that gear(s) can be taken from a H41/H42 transfer case and be swapped into a H55/split transfer case to get a lower crawl ratio? And if so, would it ONLY effect the low 4wd range?
Just to confirm, I have a 1989 JDM BJ74 with a 5 speed. I will be getting the low gear out of the 4 speed t-case and using it with the input gear out of my 5 spd?the early 4 speed (small idler shaft) low range gears were 2.28.
the early 5 speed (small idler shaft) low range gearing was 1.96
the later 5 speed (large idler shaft) low range gearing was 1.96
the later 2H auto (large idler shaft) low range gearing was 2.48
changing out the low range gear sets affect the low range only (obviously)
if you are swapping the gear set then make sure you use the proper imput gear for the tcase on the tranny, the 4 spped imput gear and the 5 speed imput gear are different.
