Frequently Asked Questions
Q: What chain pitch is this front sprocket designed for?
A: This sprocket is engineered specifically for 428 chain size applications.
Q: How do the mud grooves help performance?
A: The machined self-cleaning mud grooves at each tooth prevent mud and debris buildup, reducing wear on both the chain and sprocket teeth.
Q: Is mounting hardware included?
A: No, mounting hardware is sold separately. Reuse your OEM countershaft retaining hardware if in good condition.
Expert Pro-Tip: Always inspect your countershaft seal and retainer clip whenever replacing a front sprocket; a worn retainer clip can allow axial play and damage the output shaft splines.
