Koswork Mod 1 M1 13T Lightweight Hardened Steel RC Pinion Gear 5mm Shaft - KOS03006-13

The Koswork KOS03006-13 is a Mod 1 13-tooth pinion gear designed for RC cars and trucks running a 5mm motor shaft. Built from lightweight hardened steel, this M1 pinion gear is engineered to handle the demands of competitive and high-performance RC driving while keeping rotating mass to a minimum. The inclusion of a high-torque set screw ensures the gear locks securely onto the motor shaft without slipping under load.

Key Features

• Mod 1 (M1) tooth pitch for compatibility with standard Mod 1 spur gears used across a wide range of 1/10 and 1/8 scale RC vehicles
• 13-tooth count suits setups where higher torque and acceleration are prioritised over top-end speed
• Hardened steel construction resists wear and chipping during extended running or racing use
• Lightweight design reduces rotational inertia compared to standard steel pinions
• High-torque set screw included for a firm, reliable fit on 5mm motor shafts

Compatible With

• RC cars and trucks fitted with a 5mm shaft motor
