Optimize power transfer and drivetrain reliability with the Tekno RC TKR4184 “M5” Hardened Steel Mod1 Pinion Gear (24T), engineered for high-performance 1/8 scale electric vehicles and other MOD1 applications. Precision CNC machined from hardened steel, this pinion gear is lightened for efficient, quiet operation while maintaining exceptional durability under extreme racing and bashing conditions. The oversized M5 set screw design provides superior holding strength and reduces the risk of stripping, ensuring the gear stays securely in place during operation. Featuring a 5mm bore and standard MOD1 pitch, it is compatible with a wide range of Tekno platforms including the EB48 series (EB48, EB48.2, EB48.3, EB48SL), ET48 series (ET48, ET48.3), and SCT410 series (SCT410, 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 fast and precise for dialing in optimal performance.
