Race-Focused Replacement for 3RACING Cero

The 3RACING SAK-C143 outer shaft hub with a 3.5mm bore is a direct replacement intended to restore precise drivetrain geometry on the Cero platform. Use this hub to maintain predictable handling and minimise variable play during competitive use.

Application and Fitment Details

Produced to the Cero specification, the hub integrates into stock assemblies and supports consistent wheel alignment. Accurate fit reduces drivetrain lash and helps preserve setup adjustments between runs.

Setup and Maintenance Notes

Before installation, verify axle dimensions and mating faces for damage. Fit the hub using correct fasteners and torque values, then confirm free rotation under load. Include this check in your regular pre-event maintenance routine to ensure consistent performance.

How does this hub affect handling consistency?

A correctly fitted hub reduces drivetrain play, which improves repeatability in steering and throttle response between laps, aiding consistent setup tuning.

Should I check axle runout after fitting?

Yes, checking axle straightness and runout helps ensure the hub seats evenly and does not introduce bias into the drivetrain that can affect tyre wear or handling.

Any quick trackside checks?

Carry spare SAK-C143 hubs and inspect bores for wear between heats. Confirm fastener torque and listen for unusual drivetrain noise after each run to spot issues early.
