Frequently Asked Questions

Q: Does this sprocket include mounting hardware?
A: No, mounting hardware is not included; inspect your existing countershaft securing hardware for wear prior to installation.

Q: How do the self-cleaning mud grooves help on the track?
A: The machined grooves channel mud and dirt away from the contact points, protecting both the chain and sprocket from premature hook wear.

Expert Pro-Tip: Always replace your front and rear sprockets together along with a fresh chain. Mixing a new front sprocket with a worn chain leads to rapid tooth deformation and drastically shortens component lifespan.
