Technical Brief: 3Racing CRA-130 61mm Swing Shaft

The 3Racing CRA-130 is engineered for Crawler Ex platforms to provide a stable pivot within the drivetrain. Its 61mm dimension supports predictable geometry under load, which aids in maintaining wheel timing during demanding manoeuvres.

Performance Notes for Tuners

  • Precision Engineering: Dimensioned to align with Crawler Ex mounting points to preserve driveline angles and reduce unwanted play.
  • Durable Construction: Specified to withstand repeated impact cycles common in competitive crawling without premature deformation.
  • Enhanced Drivetrain Efficiency: Stabilises torque transmission to limit shock loading on gears and bearings, supporting consistent lap to lap performance.

What alignment checks are recommended after fitment?

Verify axle centring across suspension travel, inspect for lateral play, and torque fasteners to manufacturer recommendations to maintain repeatable geometry.

Any setup tips for competitive use?

Check driveline alignment after ride height and link adjustments, and pair the CRA-130 with matched link lengths to preserve predictable handling.

How should teams inspect the shaft between events?

Inspect for scoring at bearing contact points, ensure pivots move freely, and replace if any deformation or excess wear is detected to avoid performance degradation.
