3Racing 3RAC-PG6443 Competition 64 Pitch 43T Hardened 7075 Pinion  [3RAC-PG6443]

Competition Grade 64 Pitch Pinion

The 3Racing 3RAC-PG6443 43T pinion is engineered for racers who demand accurate tooth geometry and stable drive characteristics. Manufactured from aerospace-grade 7075 aluminium and finished with a hard coating, this pinion reduces wear while keeping rotational mass low, making it suitable for fine tuning gear ratios in competitive setups.

Material and Finish for Repeatable Performance

7075 aluminium provides a high yield strength that resists deformation under torque, while the hard coat improves surface hardness to extend service life. This combination supports repeatable mesh behaviour session after session, which is important when optimising acceleration and top speed through gear selection.

Tuning-Focused Tooth Profile

Cut to 64 pitch with 43 teeth, the pinion delivers precise engagement with matching spurs to ensure linear power transfer and consistent drivetrain response. Its predictable behaviour makes it straightforward to evaluate gearing changes during setup and to extract reliable lap time improvements.
