FAQ

What is included with Team Associated ASS92149? The set contains one 72-tooth 48-pitch centre differential spur gear and one 78-tooth 48-pitch centre differential spur gear.

What is the difference between the 72T and 78T spur gears? With the same motor pinion, the 72T spur produces taller gearing while the 78T spur produces shorter gearing. The 78T option generally provides more mechanical reduction, while the 72T option reduces the overall gear ratio. Motor temperature and track conditions should be monitored whenever gearing is changed.

Does ASS92149 fit the RC10B74.2 and RC10B74.2D? Yes. Team Associated officially lists both the RC10B74.2 and RC10B74.2D among the compatible vehicles for part 92149.

Does this set include a centre differential? No. This package contains the two spur gears only. The complete RC10B74 centre differential assembly is a separate part.

Important Notes

• Both supplied gears are 48 pitch and require a compatible 48-pitch motor pinion
• Check the exact vehicle and drivetrain configuration for part 92149 compatibility before installation
• Centre differential, motor pinion and other drivetrain components are not included
• Recheck gear mesh and monitor motor and ESC temperatures after changing spur gear size
