Overview
The Hot Racing Steel Spur Gear 63T 0.5M for Arrma Mini upgrades the small-scale Arrma drivetrain with a hardened steel gear designed to handle brushless power and repeated bashing. The 63-tooth, Mod 0.5 profile replaces the stock gear with a more durable direct-drive solution for drivers who want less slip and longer gear life.
