This is a Novak 5mm Bore Steel Mod 1 Pinion 3-Pack. Novak hardened steel
pinion gears are now available in three packs! This allows drivers to
experiment with gear ratio changes, while at the same time saving money
by giving drivers the option to purchase a pack of gears, instead of
buying individually! These heavy-duty gears are a necessity when
converting 1/8-scale nitro off-road vehicles for brushless electric use.
The gear pitch fit's seamlessly with the Mod 1 spur gears commonly
found on 1/8-scale Nitro vehicles and will work perfectly with Novak’s
HV High-Voltage Brushless Motors, as well as any other brushless motor
with a 5mm output shaft.
