3RACING 48 Pitch Spur Gear 91T - 3RAC-SG4891 Racing Grade Spur  [3RAC-SG4891]

Precision Spur for Racing Setup Work

The 3Racing 48 Pitch Spur Gear 91T, part 3RAC-SG4891, is presented for racers and tuners who prioritise stable gear engagement and repeatable drivetrain response. It installs into standard 1/10 transmissions and supports incremental ratio changes during setup sessions.

Consistent Mesh and Power Transfer

The 91T configuration moderates torque pulses and promotes even tooth contact, which is beneficial when refining gear mesh and minimizing heat under race conditions.

Tuning Benefits and Integration

Use this spur when testing pinion steps to find the best compromise between acceleration and top speed. Check backlash and alignment carefully during setup to protect bearings and reduce drivetrain losses.
