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

Precision Pinion for Consistent Driveability

The 3Racing 3RAC-PG6443 64 pitch 43T pinion is a practical upgrade for model racers seeking stable gear engagement. Manufactured in 7075 aluminium with a hard coated finish, the pinion is designed to stand up to repeated use while keeping weight down. The 43-tooth count supports even power flow for on-track performance.

Long Life from Quality Materials

7075 aluminium gives this pinion an excellent strength to weight ratio, helping resist deformation under load. The hard coating protects tooth surfaces from premature wear, improving longevity compared with untreated parts. This makes it a sensible choice for regular club use and practice sessions.

Accurate Meshing for Predictable Performance

Cut for 64 pitch compatibility, the 43T design provides a reliable engagement profile that helps maintain driveline efficiency. Fitment with matching spurs yields smooth acceleration and consistent top end, aiding setup work and tuning for varied track conditions.
