Race-oriented 3RACING 64 Pitch Pinion Gear 55T

The 3RACING 64 Pitch Pinion Gear 55T is produced from 7075 aluminium and treated with a hard coating to maintain tooth geometry under sustained load. It is suited for tuners seeking predictable mesh and minimal wear in competitive 64 pitch systems.

Racing-focused features

  • Material: 7075 aluminium provides a high strength to weight ratio for responsive throttle response and durable service.
  • Coating: The hard treatment reduces abrasive wear, preserving precise tooth form for consistent gear meshing.
  • Compatibility: Intended for high-performance RC platforms using 64 pitch gear trains.

Setup and tuning notes

Pair this pinion with a properly matched spur and set an accurate mesh using a feeler or shim method. For race setups, recheck mesh after a few runs to ensure no movement has occurred in the motor mount or pinion clamp.

What mesh clearance should I aim for in race trim?

Aim for a minimal but safe clearance that avoids binding; a paper-thin feel with no play under load is common practice. Consistent checks before events are recommended.

Is 7075 preferable to other alloys for pinions?

7075 offers improved tensile strength versus typical aluminium grades, making it a common choice where low mass and high load capacity are required in competition parts.

How should I monitor wear during a race weekend?

Inspect tooth faces between practice and qualifiers; look for rounding or surface flaking. Swap to a spare if wear is detected to protect the spur and maintain lap consistency.
