11 Tooth Extra Hard Blackened Steel 32p Pinion for 5mm Motors (RRP8611)

The 11-tooth extra-hard blackened steel pinion gear is a 32-pitch option designed for 5mm motor shafts, built for durability in demanding RC setups. Made from high-carbon steel and heat-treated to boost surface hardness, it resists wear when paired with metal spur gears. Each pinion is precision machined and stamped with its tooth count, and includes a 4mm set screw; a 2mm Allen wrench (not included) is needed to tighten it.

Designed for heavy-duty use on 5mm-shaft motors across popular brands such as Traxxas, Associated, and HPI, it pairs with both 32-pitch and .8-module gears for flexible gearing options. For motors with 1/8-inch shafts, a reducer sleeve may be required to ensure proper fit and smooth engagement.
