Street and Club Use with 3RACING 3RAC-SG4877

The 3RACING 3RAC-SG4877 48 pitch spur gear with 77 teeth is a solid option for hobbyists refining gear ratios in 1/10 on-road cars. Its tooth profile promotes steady engagement and predictable wear characteristics so you can tune ratios without surprises.

Fitment and Chassis Choices

This spur gear suits many 1/10 scale on-road chassis that use 48 pitch gearing. Pair it with a compatible 48 pitch pinion to keep power transfer efficient and reduce premature wear on drivetrain parts.

Setup and Maintenance Advice

Adjust the motor position to achieve a clean mesh with minimal slop while avoiding binding. Check the gear mesh during routine maintenance and correct any misalignment or excessive play to preserve performance.

Will this 77T spur fit most 1/10 touring cars?

It fits many 1/10 on-road platforms that specify 48 pitch spur gears, but confirm the chassis mounting and pinion compatibility before installing.

How should I set the spur and pinion mesh?

Use the paper or feeler method to set a small consistent gap, then rotate the drivetrain to ensure smooth engagement with no binding or excessive backlash.

How often should I inspect the spur gear?

Check the gear during regular service intervals and after any heavy impacts; look for chipped teeth, uneven wear, or loose fixings and replace if needed.
