Frequently Asked Questions

Q: Does this sprocket include mounting hardware?
A: No, mounting hardware is not included unless specified; inspect your existing hardware during installation and replace if worn.

Q: How do self-cleaning mud grooves help performance?
A: The machined grooves at each tooth channel away dirt and mud, reducing friction and preventing premature chain and sprocket wear.

Expert Pro-Tip: Always replace your front sprocket, rear sprocket, and chain as a complete set when possible. Putting a new front sprocket on a worn chain will drastically accelerate wear on the new component.
