Koswork 48P 38T Aluminium Thin Lightweight RC Pinion Gear - KOS03001-38

The Koswork KOS03001-38 is a 48 pitch, 38 tooth aluminium pinion gear designed for use in competitive RC car builds where reducing drivetrain weight is a priority. Machined from aluminium rather than steel, this thin-profile pinion gear keeps rotating mass low, which can benefit throttle response and motor efficiency in race applications. The 48P tooth pitch is a widely used standard in touring car, pan car, and other on-road RC racing classes, making this a practical option for builders looking to fine-tune their gear ratio with a lightweight component.

Key Features

• 48 pitch (48P) tooth profile compatible with standard 48P spur gears used across many RC racing platforms
• 38 tooth count for gear ratio tuning in competitive or performance builds
• Aluminium construction reduces weight compared to steel pinion gears, lowering rotating mass in the drivetrain
• Thin lightweight design suited to space-conscious motor and gearbox arrangements
• Koswork part number KOS03001-38 for straightforward identification and reordering

Compatible With

• RC cars and buggies using 48 pitch (48P) spur gear systems
