Enhance drivetrain strength and performance with the Tekno RC TKR4187 “M5” Hardened Steel Mod1 Pinion Gear (27T), precision CNC‑machined from hardened steel for durability and efficient power transfer under demanding racing and bashing conditions. The lightweight yet rugged design promotes smooth, quiet operation while the oversized M5 set screw delivers a secure, slip‑resistant grip on the motor shaft. With a 5 mm bore and standard MOD1 pitch, this gear is compatible with a wide range of 1/8 scale vehicles that use MOD1 pinion gears, including popular Tekno platforms such as the EB48 series (EB48, EB48.2, EB48.3, EB48SL), ET48 series (ET48, ET48.3), and SCT410 series (SCT410, SCT410.3). Laser‑etched tooth markings make gear identification quick and easy, so you can dial in optimum speed and acceleration for your setup.
