TKR4182 "M5" Hardened Steel Mod1 Pinion Gear w/5mm Bore (22T)

Improve drivetrain efficiency and reliability with the Tekno RC TKR4182 “M5” Hardened Steel Mod1 Pinion Gear (22T), designed for high-performance 1/8 scale electric vehicles and other MOD1 applications. Precision CNC machined from hardened steel, this pinion gear is lightened for smooth, quiet operation while maintaining exceptional durability under demanding racing and bashing conditions. The oversized M5 set screw provides superior grip on the motor shaft and helps prevent stripping during installation or removal. Featuring a 5mm bore and standard MOD1 pitch, it is compatible with a wide range of Tekno platforms including the EB48 2.1, ET48 2.0, and SCT410.3, as well as other 1/8 scale vehicles requiring a MOD1 5mm pinion gear. Laser-etched tooth markings allow for quick identification, making gear changes easy when dialing in optimal speed and acceleration.
