Does anyone know which year/model TCs came with 3.37:1 gears stock?

Thanks,
I believe 2001 Road King Classics and Ultra Classics.

This part of the quote confuses me. I have an '02 Deuce and the quote seems to skip the '02. I am wondering, do I need to remove the primary to verify or do I NOT have the 3.37 from the factory?

I have a new comp sprocket but am wating to order the Clutch Basket.

"quote from little bear"
#37846-99a came on all 1999 HD EFI models and was first introduced in 1999 as per the "-" designator. It was used on 2000, 2001 and EFI models but no longer used in 2003 when all models got the 3.15 gearing.
To go to 3.37 gearing you also need P/N 40269-85A countershaft sprocket which was used on all HD models through 1993 then only on the later EFI models through 2001.

Let us know how it goes and if there are any gotchas to look for. I have an 03 FI Heritage I am going to try it on in the next month if I can get some time off on the weekends. I have read all the posts I can find here and on other sites. I try to lurk and learn as much as possible and heard the tricks on breaking the loctite 262, the torque methods on the comp. nut, I also have the service manual, but first hand exp. from someone first timing it always helps. Good Luck!


:cheers:

I did the 95" upgrade and Gear drive cam install myself. And, at the same time, installed a new drive belt. Mechanically I will have no problems. I just hope I am impressed with the upgrade.
