Refined spiral gearing from 3Racing for smoother crawler handling

The 3Racing CRA-133 30T x 0.9mm spiral gear is made to replace the standard unit on Crawler Ex Real machines. It delivers steady tooth engagement and improved durability so you can focus on delicate throttle control and accurate line picking. The design supports reliable torque transfer in low speed scenarios.

Reasons to fit the CRA-133 in your build

With careful manufacturing, the CRA-133 provides practical benefits for serious crawlers:

Durability: Designed to resist the repeated impacts and loads found in technical crawling.
Precision Engineering: Thirty teeth at 0.9mm profile yield predictable, low backlash operation.
Seamless Compatibility: Purpose made for the Crawler Ex Real family for direct installation.

Can this replace the stock gear without changes?

Yes, the CRA-133 is intended as a plug-in replacement for Crawler Ex Real gearboxes when the gearbox is in standard configuration.

Does spiral cut reduce gear noise?

Spiral teeth typically smooth engagement which can lower impact noise and distribute load more evenly during slow speed crawling.

Any routine checks after fitting?

After installation, confirm torque on mounting screws and verify gear mesh after a short run to ensure no unexpected wear or binding.
