Koswork 48P 31T Aluminium Thin Lightweight RC Pinion Gear - KOS03001-31

The Koswork KOS03001-31 is a 48 pitch 31 tooth aluminium pinion gear designed for use in electric RC cars running a 48P drivetrain setup. Machined from aluminium rather than steel, this pinion gear is notably lighter than standard steel alternatives, making it a popular choice for racers and builders looking to trim rotating mass from the drivetrain. The 48P tooth pitch is a widely used standard in 1/10 scale touring car, buggy, and stadium truck classes, so this gear slots into a broad range of competition and club-level builds.

Key Features

• 48 pitch (48P) tooth profile suits motors and gear systems designed around the 48P standard
• Aluminium construction reduces weight compared to steel pinion gears
• Thin profile design helps in tight motor-to-spur gear spacing situations
• 31 tooth count allows fine-tuning of gear ratio to balance acceleration against top speed
• Part number KOS03001-31 identifies this specific tooth count within the Koswork 48P pinion range

Compatible With

• Electric RC cars and buggies using a 48 pitch spur gear and motor with an appropriate shaft diameter
• 1/10 scale touring cars, buggies, and stadium trucks running 48P drivetrains
