Arrowmax AM-348046 48P 46T 7075 Hard Pinion Gear - Precision Upgrade  [AM-348046]

Precision and durability for RC gear trains

The Arrowmax AM-348046 pinion gear is machined from 7075 hard aluminum to deliver consistent tooth geometry and extended service life. This 48P 46T pinion balances light weight with strength to suit a variety of RC car setups.

Built for strength and steady operation

Engineered for hobbyists who demand reliable meshing, the 7075 hard material improves wear resistance without adding unnecessary mass, making it suitable for high rpm use in tuned setups.

Compatibility and typical uses

Intended for transmissions that accept a 48-pitch 46-tooth pinion, this component fits neatly with matching spur gears. It is a straightforward upgrade or replacement for worn factory pinions.

Installation tips from experienced builders

• Set a correct gear mesh by checking contact pattern under slow rotation to avoid premature tooth damage.
• Inspect the pinion regularly and replace if you see tooth deformation or heavy scoring.
• Secure the set screw with a medium-strength thread-locker and torque to the motor mount specification.
