Direct-fit 47T spur for ARRMA 1/5 models

Designed as a direct-fit spare or stronger aftermarket option, this spur matches the factory 47T, module 1.0 form used on ARRMA 1/5 Kraton and Outcast trucks while employing 20CrMnTi steel to improve resistance to wear and fatigue during intensive use. Suitable for both RTR and EXB variants running powerful brushless systems.

Fitting guidance: inspect and clean the gearbox before fitting, verify the motor pinion is a 1.0 module pitch with the correct teeth, and set gear backlash after mounting. Preserve original shim stacks when possible and avoid overtightening fasteners to prevent bearing preload issues.

Impact on setup: upgrading to a higher-strength spur reduces the likelihood of tooth wear without changing the numeric gear ratio if the same 47T is retained; remain attentive to pinion selection and ESC or slipper adjustments for performance tuning.

Which ARRMA models will accept this 47T spur?

The spur is compatible with the listed ARRMA 1/5 Kraton and Outcast RTR and EXB variants that specify a 47T, module 1.0 factory item. Check your parts list to confirm the original tooth count and module.

Will it fit EXB roller versions without modification?

Yes. The 47T M1.0 profile is used across RTR and EXB versions shown in the compatibility list; ensure correct pinion pitch and mounting before running.

What original part numbers does this replace?

Refer to the original part reference shown above for cross-checking: ARA310920 and ARA311051 are the listed identifiers to compare with your vehicle's parts list.

Any torque guidance for gearbox screws?

Use manufacturer recommended torque for gearbox hardware where available; tighten incrementally and avoid bottoming screws to prevent preload on bearings that can affect gear engagement.

Does swapping the spur affect balance or vibration?

A like-for-like 47T replacement retains balance characteristics; inspect the drivetrain after installation and run a short test to check for any unusual vibration or noise.
