This seems to work well. I like the one piece design. Strong so far. We will see what a summer worth of cranking will do to it.

Doin great, even with only one starter bolt holding it in. Sometimes there's no bolt and it works well. I've road it pretty hard and after 4 months, it's thrown the seal out and I've got to replace it.

This has been a very good drive. I machined the outer primary bushing a little snug. Miss engaged pretty often. Keep in mind I am running a belt drive primary! And my fault of to tight of tolerance. After a little riding, it is flawless! 110” high compression big cam S&S !

This replacement jackshaft on my 2001 dyna was a quick install and seems to work better than the original multi piece assembly . Hoping it stops the problems I have had with tearing up starters and ring gears

What a great fix for the old, worn and far too many piece jackshaft assembly! I love this product!
