The SER440136 pro-level differential unit replaces the front or rear diff on the Serpent Mini Spyder monster truck platform. This description covers where the unit fits in the drivetrain, fitment notes, and its effect on handling and traction.
As a modular unit it installs into the Mini Spyder layout without modifying chassis geometry and is suitable for hobby-grade electric RTR MT rigs. During installation confirm gear mesh and preload, check driveshaft alignment, and ensure the gearbox face aligns with SER440001-series mounting points.
Install SER440136 wherever the Mini Spyder drivetrain calls for a pro front or rear differential; the part delivers consistent slip characteristics and seats to the SER440001 mounting arrangement with routine checks.
