Koswork 32P M0.8 25T Lightweight Hardened Steel RC Pinion Gear 5mm Shaft - KOS03000-25

The Koswork KOS03000-25 is a 32P M0.8 25-tooth pinion gear designed for RC cars running a 5mm motor shaft, offering a lightweight hardened steel construction with a high-torque set screw for a secure, rattle-free fit. Pinion gears are a critical drivetrain component, and this one is built to handle the stresses of competitive and bashing use without adding unnecessary rotating mass. The included high-torque set screw ensures the gear locks firmly onto the motor shaft, reducing slippage under hard acceleration.

Key Features

• 32 pitch M0.8 tooth profile — compatible with M0.8 spur gears commonly used across a wide range of 1/10 and 1/8 scale RC platforms
• Hardened steel construction provides greater wear resistance compared to standard steel or aluminium pinions
• Lightweight design reduces rotational mass, which can help with throttle response in performance builds
• 25-tooth count suits a range of gear ratio setups — check against your spur gear tooth count to confirm your desired ratio
• High-torque set screw included for a firm, positive lock on 5mm motor shafts

Compatible With

• RC cars and buggies using M0.8 (32P) pitch spur gears
• 5mm motor shaft motors
• Widely compatible with 1/10 scale electric on-road and off-road RC platforms using standard M0.8 drivetrain components
