I have a Jdm J1 cable trans. I was wondering if anyone offers a final drive that would fit my transmission. For those of you not familiar with the trans it has the smaller 1 inch input shaft and the gear set is 3.23, 2.105, 1.458, 1.107, .848 with a 4.40FD. So the gear set is actually a little closer than the 98 spec ITR. I was wondering if anyone offered a final drive some where in the range of 4.78-4.92?

 

MFactory makes a 4.928 FD specifically for the cable B16.

 

But isn't it designed for the 92-93 style trans with the larger input shaft 1 & 1/16th inch, instead of the smaller 1 inch input shaft?

 

After visiting their web page and doing some reading, it appears that the 4.928FD that MFactory offers is indeed for the 88-91 B16A cable trans. So it should work. I will be getting in touch with MFactory Tech support to clarify my findings. Big thanks to Aquafina. On a side note what do you guys think about their R.E.M. polishing services. Also MFactory vs A.T.S. which has a better FD?

 

It is for the small spline as the big spline can use a hydro FD. REM is good, though you won't see much of a benefit just having the FD done (aside from longer service life of the FD). As far as MFactory vs ATS, see how many broken MFactory gears you can find by searching, now see how many broken ATS you can find. Totally different manufacturing process and materials used.
