"The clutch basket part # is 37846-99A 37 tooth. The motor sprocket is #40269-85A 24 tooth."

If you type in "3.37:1" in the "Search" term, you get a bunch of hits; that's where the above came from.

If you go to Chicago HD's website, you can type in those PN's and it will, if they are accurate, confirm the description, and provide pricing.

The gear change uses the same chain as the 3.15:1 set-up.

When making the change did you buy a new roller bearing as well or re use it? 37906-90 part number

Upgraded Gearing on 06 Cop Glide to 3.37 to 1

Worth the time and effort. While we were in there, replaced primary chain and tensioner shoe.

Good bang for the buck upgrade using factory parts.

Thanks to all for the assistance.

Good for you, Tom--glad you like it. I'd like to know how you compare the 3.37 to the 3.15 for two-up riding.

I can tell you how I like it....I love it. I have ridden thousands of two-up miles with the bike loaded down with 60+ lbs of gear. At anything about 50 mph, there is no need to downshift. At 60+ MPH, you are right in the "sweet spot". When you crack the throttle, it pulls like a freight train very hard up to 90-95. It is great for making passes without having to downshift.
