Arrowhead Harley-Davidson 10T Jackshaft

Arrowhead is known for providing reliable electrical and starting components for Harley-Davidson motorcycles. This 10T Jackshaft is a prime example of their focus on improving performance and simplifying installation. It's built to give your primary drive more torque while preventing the jackshaft from binding, a common issue that can cause problems down the road.

What's neat about this design is how they've moved the cushioning spring to the back of the shaft. This clever change means you don't need an extra inner primary support bearing, which makes putting this jackshaft in a whole lot easier. You get improved torque delivery and a more straightforward installation, all in one well-made part.
