Overview
The HPI Racing 87-Tooth 48-Pitch Spur Gear is a genuine factory replacement spur gear for the HPI E-Firestorm. The 48-pitch tooth profile is a popular standard size for 1/10 scale electric vehicles, providing a balance of strength and gear-mesh fineness.
Worn or chipped spur gears cause noise, slop, and broken teeth — fresh OEM gears restore quiet, smooth power transfer.
