3RACING 64 Pitch 39T Pinion 3RAC-PG6439 (7075 Hard Coated)  [3RAC-PG6439]

Compact upgrade for stronger drivetrain performance

The 3RACING 64 Pitch Pinion Gear 39T gives a durable, low weight option for RC drivers wanting improved drivetrain response. The 7075 aluminium build and hard coat help the pinion sustain demanding runs while keeping gear play minimal.

Strength without extra mass

Using 7075 aluminium keeps the part light but stiff, which helps reduce rotational inertia. The hard coat improves surface toughness so the gear resists chipping and wear from frequent racing or practice sessions.

Precision fit for smoother power transfer

With a true 64 pitch profile, the 39T offers clean engagement with compatible spur gears to reduce slop and drivetrain noise. It suits many 1/10 scale vehicles that specify 64 pitch components.

Ready for race day tuning

Install this pinion when dialing in gear ratios for speed or acceleration. Its construction helps maintain consistent teeth engagement during high RPM runs, giving predictable performance at the track.
