Title: Aftermarket Gears - Need Info on Teeth & Ratios for Yukon HD's & Baldwins
Post by: havinnoj on March 17, 2014, 09:15:22 PM

I'm compiling gearing info and need to know whether the Yukon's and Baldwin gears were different from the OEM.  Right now I'm assuming they were the same as the later years but need to know for sure.  Besides Nate McCoy's billet transmission (which I have ratios for) and Arlan's new 250R tranny gears, I don't think there are any others aftermarket manufacturers.  Let me know if I'm missing one.

I have a Baldwin set. Same ratio as stock 87-89. 2nd thru 6th countershaft only. Yukons were the same.
 I tried to get info on marks gears a couple of times, as far as material and so forth. I think all Marks plans went to Duncan/Yukon if I'm not mistaken.  I may have to go over and poke him personally to get some info.
They were $725 when I bought them from Mark.

Thanks for the confirmation Bill.  I always thought Mark's gears were a bit different than the Yukon ones.. maybe not though.  That would be cool!  I remember when you could get a full Yukon set for under $300!  I still have an unopened set I can't quite make myself open up :D
