High-Strength Arrowmax AM-348046 7075 Hard 48P 46T Pinion  [AM-348046]

Accurate machining for consistent gear engagement

The Arrowmax AM-348046 pinion is precision machined from 7075 hard aluminium to provide stable tooth profiles and long-lasting service. The 48P 46T specification delivers predictable gearing for a wide range of RC cars.

Why this 7075 48P 46T pinion stands out

7075 hard aluminium offers a good mix of toughness and low weight, helping to reduce rotating mass while resisting wear under normal running conditions. This makes the part suitable for both club racers and weekend hobbyists.

Where to use this pinion

Fit this 48-pitch, 46-tooth pinion in gearboxes designed for 48P pinions. It pairs with compatible spur gears and is ideal for replacing worn or damaged pinions during routine maintenance.

Pro tips for fitting and care

• Check the gear mesh visually and with a slow rotation to ensure even tooth contact across the faces.
• Keep the pinion clean of debris and check for wear after high-mileage sessions.
• Apply a dab of thread-locker to the set screw and tighten securely to prevent slippage.
