Precision Gear Upgrade with 3Racing 3RAC-SG6485

Fit the 3Racing 64 Pitch Spur Gear 85T to refine your model's drivetrain characteristics. The 85 tooth layout promotes steady power transfer and helps smooth acceleration response for tighter control on track or practice sessions.

Performance Characteristics

The 3Racing spur is intended to provide stable torque handling and consistent meshing under varied running conditions. It supports fine tuning to balance top speed against acceleration according to driving preferences.

Compatibility Notes

This spur suits many 1/10 scale vehicles as either a replacement part or a tuning upgrade. Confirm pinion compatibility and centre spacing before finalising installation to ensure correct mesh.

Will the 85T change my gearing ratio significantly?

The effect depends on your pinion size; generally an 85T spur yields a slightly lower final ratio compared with smaller spurs, favouring acceleration.

How should I check for correct mesh?

Set a small amount of backlash with a paper or feeler, run in slowly and then recheck to prevent premature tooth wear.

Suitable for competition use?

It is commonly used in club and practice environments; verify compatibility with your class rules and drivetrain layout for race events.
