High-Strength 7075 Pinion by Arrowmax AM-348021

The Arrowmax AM-348021 48P 21T pinion gear provides a robust metal alternative for RC drivetrains. Constructed from 7075 aluminium, it resists wear while keeping engagement smooth across different setups.

Fine-Tuned Tooth Profile for Stable Drive

Careful machining of the 48P 21T teeth ensures accurate meshing and helps reduce uneven load on the spur gear. That stability supports predictable drivetrain behaviour and longer component life.

Wide Use Across Common RC Cars

Featuring a standard 48 pitch and 21 teeth, the AM-348021 suits many types of electric and nitro cars. It is a straightforward option when adjusting gearing for acceleration or top speed preferences.
