Durable 48P Spur Gear from 3Racing

Built for everyday use and harder weekend runs, the 3Racing 48 pitch spur gear with 73 teeth delivers predictable engagement for a variety of RC drivetrains. It is a straightforward replacement or upgrade for hobbyists aiming to improve drivetrain reliability without complex modifications.

Which models typically use a 48 pitch spur gear?

A wide range of hobby 1/10 scale on-road and some short-course models use 48 pitch gearing; always confirm pitch and tooth count before fitting.

How does a 73 tooth spur affect gearing?

A 73T spur tends to reduce top speed and increase acceleration compared with fewer teeth; pair it with the appropriate pinion to tune speed versus torque.

What basic maintenance keeps the gear lasting longer?

Keep the gear free of grit, check for chipped teeth, ensure correct mesh, and replace if wear becomes noticeable to avoid drivetrain damage.
