Competition Grade 3Racing 64 Pitch Pinion 61T

Engineered for tuning and track use, the 3RACING 3RAC-PG6461 pinion is CNC-grade in concept and uses 7075 aluminium with a hard coat to maintain tooth integrity under repeated load cycles.

Technical Highlights

  • Material: High tensile 7075 aluminium for rigidity and minimal flex under torque.
  • Surface Hardness: Durable hard coating to reduce micro-abrasion and extend operational life in demanding conditions.
  • Fitment: Built to match standard 64 pitch systems; verify bore tolerance and shaft concentricity for precision fit.

Optimised Drive Characteristics

The controlled tooth profile promotes consistent mesh and repeatable power transfer, supporting predictable drivetrain behaviour for setup refinement and lap consistency.

What mesh clearance is recommended for competition use?

Start with a conservative backlash setting and run short load tests to verify contact pattern; fine tune for minimal slop while avoiding interference.

How should I check bore concentricity?

Inspect with a pin gauge or test-fit on a known-straight shaft; any wobble may indicate bore or shaft runout that affects mesh quality.

Is the hard coating suitable for high RPM duty?

The hard coat improves surface wear resistance, but under very high RPM and torque loads the entire drivetrain must be specified to match those stresses.
