ASC1339 Ft Alum. Pinion 21T48P

Precision metal machining replicates the exact tooth profile and gear pitch found in full size racing transmissions to elevate the mechanical authenticity of custom builds. Designed specifically to bridge the gap between various electric platforms and standard 48 pitch gear systems, this component fits a wide compatibility scale of motor setups. Hobbyists can easily pair this gear with custom motor mounts, heavy duty spur gears, and specialized gear mesh alignment tools for a complete drivetrain upgrade. The anodized metal finish provides a realistic industrial appearance that mimics professional automotive drivetrain hardware used in competitive racing. Seamless compatibility with standard motor shafts allows builders to integrate this piece into numerous scale vehicle projects without modification. Proper tooth engagement ensures smooth power transfer while preserving the intricate mechanical layout expected by dedicated scale modelers.

Features

• Precision CNC machined aluminum construction ensures optimal gear mesh and long lasting durability under intense motor loads. The lightweight material prevents excessive rotational mass from slowing down acceleration.

• Hard anodized coating protects the tooth surfaces from premature wear and tear during high speed track sessions. This protective layer also gives the gear a professional showroom quality look.

• Dual set screw retention allows for a secure lock onto various motor shaft diameters without slipping. This reliable mounting mechanism prevents unexpected gear separation during heavy acceleration.

• The 48 pitch tooth profile matches standard transmission configurations for smooth power transmission. This precise geometry reduces operational noise compared to plastic stock alternatives.

• Compact sizing fits neatly inside tight motor compartments without rubbing against chassis walls or gear covers. This careful clearance design ensures friction free operation across multiple chassis layouts.

• Laser etched tooth count markings make it easy to identify gear ratios at a glance during pit maintenance. The permanent lettering resists fading from exposure to motor sprays and workshop solvents.

• Balanced rotational weight distribution eliminates vibrations that could otherwise damage sensitive motor bearings over time. This stability promotes efficient energy conversion from the electric motor to the drivetrain.
