3Racing CRA-133 spiral gear for consistent crawler drive

The 3Racing CRA-133 is a 30T x 0.9mm spiral gear engineered for the Crawler Ex Real line. It is aimed at drivers who want reliable tooth engagement and lasting service life under frequent off-road loading. Expect smoother transitions and durable operation during extended trail sessions.

What the CRA-133 brings to your crawler

Manufactured with attention to fit and function, this spiral gear improves drivetrain behaviour:

Durability: Built to handle repeated stresses from rocks, roots and rough surfaces.
Precision Engineering: The 30T configuration gives predictable meshing and even torque delivery.
Seamless Compatibility: Specifically matched to Crawler Ex Real parts for a bolt-in replacement.

Will the CRA-133 work with heavy duty axles?

The CRA-133 is compatible with standard Crawler Ex Real transmissions; confirm axle and gearbox spacing when fitting heavy duty upgrades.

Is there a break-in procedure?

Run the drivetrain gently for the first few sessions to allow mating surfaces to seat, then recheck mesh and fasteners.

How do I check for correct mesh?

Set a small backlash and rotate the transmission by hand to verify smooth contact across the tooth face without tight spots.
