Arrowhead Harley-Davidson 9T Jack Shaft

This kit includes the Arrowhead 9T Jack Shaft, designed to give your Harley-Davidson's primary drive a bit more torque. It also helps prevent the shaft from binding up, which can be a real headache. The folks at Arrowhead have moved the cushioning spring to the back of the shaft. This is a smart move because it means you won't need an inner primary support bearing, making the installation process much simpler.

By relocating the spring, they've made this jack shaft easier to get into place. This part is all about improving the torque transfer to your primary and making sure the shaft operates smoothly without binding. It's a well-built component aimed at making a noticeable difference in how your bike's power gets to the wheel.
