Sturdy 7075 Aluminium Pinion from Arrowmax AM-348021

The Arrowmax AM-348021 48P 21T pinion gear is a solid option for RC hobbyists who want dependable parts. Crafted from high-grade 7075 aluminium, the pinion resists wear and keeps gear engagement smooth across a variety of vehicles.

Accurate Tooth Geometry for Consistent Mesh

Manufactured to tight tolerances, this 48P 21T pinion preserves correct gear alignment to minimise premature wear. Consistent meshing helps maintain drivetrain efficiency and reduces the need for frequent replacements.

Fits Many On-Road and Off-Road Setups

With a 48 pitch and 21 teeth, the AM-348021 works with a wide range of RC cars. Whether fine-tuning gearing for track pace or trail runs, this pinion gives practical compatibility and predictable results.

Can I use this pinion on both electric and nitro models?

Yes. The Arrowmax AM-348021 48P 21T is suitable for both electric and nitro RC drivetrains, provided the shaft size and pitch match your motor and spur gear.

What size wrench or tool do I need to fit this pinion?

Installation typically requires a small hex driver or pinion wrench to tighten the set screw. Check your motor shaft type and use the correct sized tool to avoid damaging the screw head.

Should I use grease or oil on the gear teeth?

A light coating of gear-safe grease on the spur and pinion interface can reduce wear and noise. Avoid heavy lubricants that can attract dirt or fling off at speed.
