Competition Grade 3Racing CAC-137 Universal Shaft

The 3Racing Cactus 2WD 66mm Universal Shaft CAC-137 is manufactured to tight dimensional tolerances to improve drivetrain stability under race loads. Its alloy construction minimises flex while preserving spline engagement for repeatable power transfer.

Performance Attributes and Fitment

CNC style finishing and careful material selection give the 3Racing 66mm shaft resilience against fatigue and wear. It is engineered to mate with the Cactus 2WD drivetrain components and supports common tuning changes without major alteration to the chassis layout.

Specifications

  • Length: 66mm
  • Compatibility: Cactus 2WD series
  • Material: High-strength alloy

A precise, race oriented component, the 3Racing CAC-137 66mm shaft suits drivers and teams focusing on consistent drivetrain response.

What tolerances should I check during installation?

Verify spline engagement length and end float, ensure concentric fit in coupling surfaces, and confirm there is no binding through the suspension travel range.

Are there recommended lubrication practices for race use?

Apply a thin, high quality synthetic grease to splines to reduce abrasive wear while avoiding excess that could attract dirt; recheck at service intervals.

Can the shaft withstand high torque brushless setups?

CAC-137 is built from high strength alloy to cope with elevated torque common in modern brushless systems, but component life depends on overall drivetrain alignment and maintenance.
