3RACING 64 Pitch 129T Spur Gear - 3RAC-SG64129 Racing Spec  [3RAC-SG64129]

Racing Grade 64 Pitch Spur for Tuned Drivelines

The 3RACING 64 Pitch Spur Gear 129T, model 3RAC-SG64129, is engineered for drivers who adjust gear ratios and mesh for peak on-road performance. The fine 64 pitch profile enables tighter engagement and predictable load transfer under acceleration.

Setup and Tuning Advantages

Its 129 tooth count offers a usable spread for ratio planning while the 64 pitch reduces backlash compared with coarser options. That combination helps drivers dial in handling balance and motor load for race conditions.

Practical Racing Notes

Installers should verify bore clearance and final mesh with a feeler or gauge, then test on practice runs to confirm temperatures and noise levels. The spur is suited to both brushed and brushless systems when the rest of the drivetrain is matched to higher output motors.
