Upgrade drivetrain precision with 3Racing CRA-133 spiral gear

The 3Racing CRA-133 is a 30T x 0.9mm spiral gear made for the Crawler Ex Real range. It is built to give consistent tooth engagement and dependable service when you tackle tight lines and rough rock sections. The design focuses on repeatable power delivery and long term reliability for serious trail sessions.

Key benefits of the CRA-133 spiral gear

Manufactured with close tolerances, the 3Racing CRA-133 offers clear advantages for crawler setups:

Durability: Engineered to resist wear from challenging off-road use and frequent throttle changes.
Precision Engineering: The 30T tooth count and 0.9mm profile provide smooth meshing and steady torque transfer.
Seamless Compatibility: Specifically made for the Crawler Ex Real series for a direct fit without extra machining.

Can I run the CRA-133 with stock transmission oil?

Yes, you can use typical crawler gear oil with the 3Racing CRA-133, but match viscosity to your driving style to reduce wear and noise.

Will this gear change gear ratio or top speed?

The CRA-133 keeps the intended tooth count and pitch so it will not alter the designed ratio when fitted to the Crawler Ex Real transmission.

Any installation tips for a smooth mesh?

Check backlash and gear alignment, run the transmission at low speed to seat the teeth, and recheck after a short break-in run.
