Stable spur gear for consistent drivetrain behaviour

The 3Racing 48 Pitch Spur Gear 74T - 3RAC-SG4874 helps lock in reliable gear engagement so your vehicle responds predictably under load. It is suitable for hobbyists wanting dependable performance during practice or recreational sessions.

Compatibility for a range of setups

This 74-tooth spur works with chassis that accept 48-pitch components, offering a straightforward replacement or an upgrade path for those refreshing their drivetrain. It is a practical choice for routine rebuilds.

Use for maintenance and fine tuning

Install this spur to replace worn gears or to experiment with gear ratio steps. Its tooth count enables subtle adjustments when selecting pinion sizes to refine acceleration and cruising speed.

Is the 74T suitable for stadium trucks?

It can be used where the truck accepts 48-pitch gears; confirm your gearbox and hub dimensions to ensure the 74T fits without interference.

Does tooth count change gearing significantly?

Changing tooth count alters final drive ratio. A 74T spur will shift the relationship with your chosen pinion, so expect measurable differences in acceleration and top-end behaviour.

What should I check after fitting a new spur?

After fitting, verify mesh, check for smooth rotation by hand, and ensure the motor and pinion clear the spur without binding across the suspension travel.
