Technical Overview of 3RACING CRA-114

The 3RACING CRA-114 shaft is a maintenance and tuning component for the Crawler Ex Real two-speed gearbox. It is intended to provide stable gear alignment and predictable engagement during competitive or setup-focused runs.

Engineering Notes

Designed to meet the gearbox geometry of the Crawler Ex Real series, the CRA-114 supports correct gear mesh and range transition. Proper installation preserves drivetrain efficiency and reduces the risk of intermittent engagement under load.

Setup and Tuning Use

For racers and tuners, the shaft is useful when optimising gearbox behaviour; combine with gear mesh checks, bearing inspection and controlled lubrication to achieve repeatable shifting characteristics.

How does shaft fit affect gear engagement?

Correct shaft seating ensures axial alignment and consistent gear contact patterns. Poor fit or incorrect shimming can lead to premature wear or inconsistent shifting.

Any setup tips for competitive use?

Verify gear backlash, replace worn bearings, and use a light, stable lubricant. Validate shifting under simulated course loads before an event.

Is the CRA-114 suitable for repeated tuning cycles?

Yes, as a service item the CRA-114 is appropriate for repeated replacement during iterative setup changes to maintain predictable gearbox behaviour.
