Smoother Torque Transfer with 3RACING 3RAC-SG4890/V2

This 3RACING 48 Pitch Spur Gear 90T Ver.2 is a practical drivetrain upgrade for hobbyists who want reliable, predictable performance from 1/10 scale vehicles. Engineered for accurate mesh and reduced vibration, it helps deliver cleaner acceleration and longer gear life.

Performance Highlights

Precision Gear Profile: The 48 pitch tooth form improves alignment between spur and pinion, cutting friction and slop.
Robust Build: Constructed to handle regular club racing and weekend bashing without premature failure.
Broad Compatibility: Works with many 1/10 scale setups, giving flexibility for street, track, and mixed-use rigs.

Fitting Notes

When fitting the 3Racing 48 Pitch Spur Gear 90T Ver.2 check that the pinion is a 48 pitch unit and set the mesh with a thin feeler or shims. Inspect mesh periodically and adjust to avoid accelerated wear.

Will this 48 pitch spur gear fit my 1/10 touring car?

It will fit many 1/10 touring and buggy platforms that use 48 pitch gearing. Confirm your pinion is 48 pitch and that the chassis has space for a 90T spur.

How do I check correct gear mesh?

Set the pinion so that teeth contact is even across the face, using a small gap equivalent to a paper shim or a gear mesh tool. Run and listen for whining as a sign to fine tune.

Is a 90T spur better for top speed or torque?

A 90T spur gives you a specific ratio that can favour higher top speed depending on pinion size. Choose pinion and battery to balance acceleration and top end for your track or surface.
