TH350 Questions

First off, I haven’t been to this site in years. It’s HUGE now- wow!!

I am interested in information about 4X4 th350’s. are they shorter than a short shaft 350? Measuring from bell housing to end of shaft, not end of case. Is the shaft splined the same as a regular 350? (28 spline) Or is it a gear that mates up with the gears in the transfer case?


Thank you for your time!

The main case is the same. The 4x output shaft sticks out the back of the case about 1''

Re: TH350 Questions

Yep,the case is the same,the difference is that on a 2wd the extension of the case for the longer shaft bolts to where the adapter plate would bolt to for a 4x4.
And as Stan said....There is a "K" in the case of a 4x4 TH350.
