Precision 48-Pitch Spur Gear for Cleaner Power Delivery

For hobbyists focused on drivetrain refinement, the 3Racing 48 Pitch Spur Gear 79T delivers consistent tooth engagement to improve power flow. The 48-pitch geometry with 79 teeth balances top speed and usable torque, making it a solid choice for both competitive runs and weekend practice.

Main Benefits for Your Build

Accurate Tooth Profile: Produced by 3Racing to maintain reliable gear mesh and reduce drivetrain lash.
Wide Compatibility: Works with many 1/10 scale setups that use a 48-pitch spur gear format.
Built for Repeat Use: Designed to handle frequent tuning sessions and regular track days.
Simple Upgrade Path: A straightforward swap when you are dialing in gear ratios or repairing a drivetrain.

Which scale and drivetrains suit this spur gear?

The 3Racing 3RAC-SG4879 is intended for 1/10 scale vehicles that accept 48-pitch spur gears, covering many touring and buggy drivetrains.

How should I set the mesh when installing this gear?

Start with a snug but not tight mesh, check backlash across multiple rotations, and fine tune while the gearbox is assembled to avoid binding.

Will changing to 79 teeth affect my speed noticeably?

Moving to a 79T spur will shift the gear ratio toward more torque; pair it with an appropriate pinion to restore top speed if needed.
