Mini Spyder SER440136 Pro front/rear differential unit by Serpent  [SER440136]

Compact differential upgrade for Mini Spyder

This pro front/rear differential unit is a direct replacement made for the Serpent Mini Spyder monster truck platform and carries the model code SER440136. Below we outline its drivetrain role, installation pointers, and tuning impact on grip and turn-in.

The modular design allows the diff to be fitted without changing chassis geometry and is aimed at hobby electric RTR MT builds. When swapping the unit, check mesh and preload carefully, confirm driveshaft alignment, and ensure the gearbox interface aligns with SER440001-series mounting points.

Compatibility

• Mini Spyder Monster truck RTR EP (SER440001)

Use SER440136 where the Mini Spyder drivetrain requires a pro-level front or rear diff; it gives a predictable change to slip characteristics and installs cleanly to the SER440001 mounting pattern.
