Serpent SER804444 40T Rear Differential Pulley Magnesium Edition  [SER804444]

Lightweight Rear Pulley for Tuned Drivetrains

The Serpent SER804444 40T rear differential pulley is a targeted weight-saving part for racers and tuners. Fabricated from magnesium, it reduces rotary mass while maintaining the stiffness required for reliable operation.

Cutting Weight with Magnesium

Magnesium parts reduce the load on the drivetrain and help the vehicle respond faster to throttle inputs. This material choice is commonly used where every gram matters.

40T Geometry for Rear Traction

With a 40 tooth layout, the pulley is calibrated to transfer torque to the rear axle smoothly, aiding stability through fast sections and when applying power out of turns.

Compatibility Notes and Fitment

Compatible with a variety of 1/10 scale differentials, the pulley fits into most standard layouts. Check alignment and clearances during installation to avoid contact with adjacent components.
