Precision spiral gearing from 3Racing for reliable crawler performance

The 3Racing CRA-133 is a 30T x 0.9mm spiral gear designed to suit the Crawler Ex Real platform. It focuses on dependable engagement and longevity so you can concentrate on line choice and control. The gear gives stable torque handoff and predictable behaviour across varied terrain.

Advantages of the CRA-133 for crawler setups

Built to tight tolerances, the CRA-133 helps improve drivability:

Durability: Designed to withstand repeated load cycles typical in technical off road use.
Precision Engineering: The 30 tooth design ensures consistent contact for smooth operation.
Seamless Compatibility: Made to drop into Crawler Ex Real transmissions without modification.

Can this gear be used in sealed gearboxes?

Yes, the CRA-133 works in sealed gearboxes provided the housing matches the Crawler Ex Real specification and you use the correct lubricant.

How does spiral cut help off road?

The spiral tooth form improves gradual engagement and spreads load across teeth, reducing impact stress during low speed crawling.

Do I need special tools to fit it?

Basic hand tools and a feeler gauge for setting backlash are usually enough; only minimal disassembly is required on standard Crawler Ex Real gearboxes.
