Racing-Caliber Spiral Gear

The 3Racing CRA-132 spiral gear is specified for the Crawler Ex Real platform and delivers an 8-tooth profile with 0.9mm face width for controlled torque delivery. Its spiral geometry helps maintain consistent contact under high load changes typical of tight courses.

Technical Highlights for Tuners

  • Durable Construction: Dimensionally stable under repeated torque cycles to support race day reliability.
  • Smooth Operation: Helical engagement reduces impact loading and aids predictable backlash behavior for precise control.
  • Perfect Fit: Engineered to integrate with Crawler Ex Real drivetrains to minimise setup time and ensure accurate alignment.

How should I set backlash for best performance?

Aim for minimal yet non-binding backlash. Tight mesh improves response but avoid zero clearance which can increase friction and heat. Adjust shims incrementally and test under load.

What maintenance keeps the CRA-132 race ready?

Regularly inspect tooth faces for pitting, clean debris from the mesh area, and apply a thin layer of metal-safe gear grease to reduce wear during repeated runs.

Any setup notes for competitive use?

Check pinion alignment, verify shaft endplay, and test in your typical running conditions. Small adjustments to motor timing and tyre selection can complement the gear's behaviour on course.
