HOBBYWING 19T 5mm 32P Steel Pinion Gear 86040010 High Strength Tuning Pinion  [HW-86040010]

Fine Tune Drive Characteristics with the HOBBYWING 19T Pinion

The HOBBYWING 19T 5mm 32P Steel Pinion Gear 86040010 is a handy upgrade for hobbyists who want to dial in their vehicle's drive behaviour. Made from durable chrome steel, this pinion lets you swap tooth counts to favour either torque or top speed within the allowed range.

How Tooth Count Changes Torque and Top Speed

Switching pinion gears directly affects how the drivetrain delivers power. Fewer teeth increase drivetrain torque for stronger acceleration and climbing, while more teeth raise the top end for faster straight line speeds. This change gives you flexibility for different race setups and off-road runs.

Fitment Details and Typical Uses

This pinion has a 5mm bore diameter and a modulus of 0.8mm, made from 40CR steel for improved wear resistance. It is commonly used on 1/8th scale monster trucks, including E-MAXX, E-REVO, and SUMMIT platforms, making it suitable for varied terrain and demanding driving.
