Frequently Asked Questions

Q: Why should I choose a split-style axle cassette over a standard one?

A: The split-style design allows for significantly easier bearing access. Instead of removing the entire axle assembly to service or replace a bearing, you can simply open the cassette, saving you valuable time during race day maintenance.

Q: Are these cassettes compatible with all kart axles?

A: These KMAC cassettes are specifically designed for 1 1/4-inch bearings and are compatible with most American-style karts. Please verify your axle diameter before purchasing to ensure a proper fit.

Q: Do these cassettes come with the bearings and mounting hardware?

A: No, the bearings and mounting bolts are sold separately. This pair includes the two CNC-machined billet aluminum cassette halves required for a balanced left/right installation.

Q: How does this upgrade improve my kart's performance?

A: By utilizing high-quality CNC-machined billet aluminum, these cassettes provide a rigid, precise housing for your bearings. This reduces rotational drag, allowing your axle to spin more freely, which results in snappier throttle response and improved power transfer to the tires.
