Serpent SER804444 Magnesium Rear 40T Differential Pulley  [SER804444]

Precision Rear Pulley for Improved Traction

The Serpent SER804444 40T rear differential pulley is a precision component aimed at improving the rear-end behaviour of competitive 1/10 scale cars. Magnesium construction keeps mass low while retaining sufficient robustness for racing use.

Advantages of Magnesium Hardware

Using magnesium reduces rotating inertia and can help the chassis settle faster after inputs. This material choice supports quicker throttle recoveries and tighter transient response.

40 Teeth for Controlled Power Delivery

The 40T design is chosen to provide even torque spread to the rear wheels, aiding predictable handling during acceleration and high speed cornering. Machined accuracy promotes smooth gear engagement.

Easy Swap for Common Differentials

Intended to fit many standard 1/10 differential systems, the pulley installs without major modifications. Verify fitment details for your specific model before completing the swap.
