Precision 48P 40T Pinion for Competitive RC

The Arrowmax AM-348040 Pinion Gear targets pilots who need precise gear ratios and robust construction. Built from 7075 aluminum, this 48P 40T pinion offers steady performance and resistance to fatigue during repeated use.

Why 7075 Aluminum Works Well

7075 aluminum provides a high strength-to-weight ratio, making it a solid choice where durability and minimal rotating mass are priorities. This helps reduce stress on the rest of the drivetrain while keeping acceleration crisp.

Where This Pinion Fits Best

Designed for 48 pitch systems, this pinion integrates with many popular gearboxes. It is well suited for high-speed circuits and technical layouts where gearing accuracy influences lap times.

What inspections should I do before running?

Confirm correct shaft diameter and secure the set screw, then check mesh with the spur gear to avoid binding or excess backlash.

Will this pinion reduce drivetrain wear?

Its hardened 7075 construction resists deformation better than softer alloys, which can lower wear on teeth under heavy use.

Can I run this on a brushed or brushless motor?

Yes, the pinion works with both motor types as long as gear pitch and shaft size match your motor and gearbox specifications.

Does the pinion come pre-anodized?

Check the product listing for finish details, but 7075 parts are commonly anodized to improve surface hardness and corrosion resistance.
