Durable aluminium pulley built for quick acceleration

The Serpent 804301 Aluminum 40T Rear Gear Diff Pulley is engineered to sharpen drivetrain response while keeping weight low. Made from aluminium, it delivers a sturdy yet light replacement for worn stock pieces.

Anodized finish and debris clearance

The anodized coating helps resist corrosion and surface wear under heavy use. Side apertures lower rotating mass and allow grit and mud to be expelled as you run, helping to prevent efficiency losses from packed debris.

Applications and rider notes

Suitable across a variety of RC rear diff setups, this 40T pulley is a practical upgrade for both competitive and recreational drivers. It is a straightforward way to improve drivetrain behaviour without complex modifications.

Will this pulley fit my current diff?

Check that your diff uses a 40T gear and that the mounting matches; if so the pulley should install without modification.

Does anodizing change friction or wear?

Anodizing mainly protects against wear and corrosion and has minimal effect on smooth operation when correctly installed.

Is it OK to run in wet or dusty conditions?

The anodized aluminium helps resist the elements, but avoid prolonged submersion and clean the pulley after wet or very dusty runs.
