HPI Racing 86870 Top Gear 18T RTR Firestorm 10T / Firestorm

This is a genuine HPI Racing 18 tooth top gear for the RTR Firestorm 10T and Firestorm. The top gear is a key link in the transmission, passing power down the drivetrain on every pull of the throttle.

Replacing a worn top gear restores quiet, positive gear engagement. This factory part fits directly in place of the original.
