64-Pitch Spur Gear, 90T - Yokomo SG-6490  [SG-6490]

Precision 90T 64-Pitch Spur

This is an RC-scale replacement spur with 90 teeth cut to the 64 pitch standard, intended for general drivetrain applications. The accurate tooth profiling reduces backlash and refines contact with the mating pinion, helping the drive run with steadier power delivery under typical electric model demands.

Pair this spur with a 64 pitch pinion to ensure proper engagement. Focus on correct mesh and bearing alignment during installation, since the component provides consistent tooth geometry for repeatable tuning and efficient power transfer inside the vehicle's gearbox or chassis arrangement.
