TKR4186 "M5" Hardened Steel Mod1 Pinion Gear w/5mm Bore (26T)

Improve drivetrain performance and durability with the Tekno RC TKR4186 “M5” Hardened Steel Mod1 Pinion Gear (26T), precision CNC‑machined from hardened steel for long‑lasting strength and efficient power transfer under demanding racing and bashing conditions. The lightweight yet rugged design helps reduce rotating mass for smoother, quieter operation, while the oversized M5 set screw provides a secure, slip‑resistant grip on the motor shaft. Featuring a 5 mm bore and standard MOD1 pitch, this pinion gear is compatible with a wide range of 1/8 scale vehicles that use MOD1 5 mm pinions, 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 size identification quick and easy when tuning for your ideal speed and acceleration setup.
