Frequently Asked Questions

Q: Is this hub compatible with all MCP brake rotors?

A: No, this specific hub is precision-engineered exclusively for 506 series rotors. It features a three-hole mounting pattern that will not fit four-bolt or other rotor styles.

Q: What size axle does this brake hub fit?

A: This hub is designed for a 1.25-inch diameter kart axle, which is a standard size for many competitive sprint and oval racing classes.

Q: Do the mounting bolts come included with the hub?

A: No, the 5/16-24 mounting bolts are sold separately. We recommend using high-quality hardware to ensure the rotor remains secure under heavy braking heat.

Q: Why should I choose a billet hub over a standard cast version?

A: Billet aluminum offers a superior strength-to-weight ratio. By reducing unsprung mass, you improve your kart's suspension response, while the increased rigidity prevents deformation during high-temperature racing conditions.
