Competition grade 48 pitch spur by 3Racing

The 3Racing 48 Pitch Spur Gear 63T is intended for tuners focused on repeatable drivetrain behaviour and predictable ratio changes. It supports fine adjustments to final drive for track tuning and is a solid choice when consistent gear engagement matters across multiple runs. Installations should prioritise correct mesh and alignment to preserve efficiency and reduce wear in race use.

Pairing depends on motor and track; start from your baseline pinion and change one tooth at a time to evaluate lap time and motor temperature.
Aim for a snug, even mesh with a small amount of backlash, check under load, and recheck after a few laps to ensure nothing has shifted.
Typical next steps include optimising pinion size for the chosen circuit, checking motor cooling, and trimming drivetrain losses with bearings and shaft checks.
