A new design that improves the stock HD design by incorporating the washer into the axle. This gives the extension more surface area to rest on. We also extended the slot for the extension so it goes all the way through the extension. We have never had an issue with the stock HD axle but this design is much better. Come as a pair.
2012+ Pro Axles
If you have a 2012+ bike, you already have the stock version part. This axle is an improvement on that design.
