RC Spur Gear 108T 64 Pitch Upgrade - Yokomo YOKSG64108  [YOKSG64108]

Why this spur matters in your drivetrain

This Yokomo spur is produced as a 108-tooth, 64 pitch replacement intended for model drivetrains. It serves as the large gear in typical spur/pinion arrangements and determines the final gear ratio and the mesh relationship with the motor pinion.

Installation notes: fit the spur concentrically onto your gearbox output hub or designated spur holder, align the pinion so teeth sit flush across the contact face, and tune motor placement or shims until engagement is even without binding. Small spacer changes often solve minor misalignment; always check rotation under gentle throttle before locking hardware.

Tuning role: selecting a 108T spur shifts overall gearing versus smaller tooth counts, altering the balance between acceleration and top speed when paired with different pinions. Employ this part to trial gearing setups for race pace, endurance, or surface traction while watching bearing integrity and motor stress to prevent excess wear.
