Broken Ring On Your Harley Dyna Or Big Twin?

So you thought you could not replace a damaged Harley OEM ring gear without replacing the entire basket?

A company called Evolution Industries is introducing what seems to be an industry first: a replacement kit for 2006.up Dynas and 2007-up Big Twins.

Unlike OEM ring gear using mild steel with only edges flame treated, Evolution Industries heat treats the entire part. Kit includes a new replacement starter pinion and clutch assembly with clutch and gear featuring 20% larger rollers for longer starter life. Made in the USA. Evolution Industries. 909-594-7969.

    Great product for later Twin Cam models. Evolution makes product right in So-cal and makes it right. Check out what this company makes in house well worth the time specially with drive line and Clutch applications.
