The Serpent 440130 gearbox cover serves as a replacement shell for the Mini Spyder MT series. It is intended to keep dirt and grit away from the transmission internals during off-road runs.
This part fits within the Mini Spyder MT family referenced in the product name; confirm your chassis code prior to ordering to ensure compatibility. It is a removable service component designed for routine drivetrain maintenance without requiring major chassis modification.
Installation guidance: detach the necessary body panels to reach the gearbox, preserve and reuse existing fixings where possible, and tighten fasteners to the recommended torque for your chassis. Carry out a clean inspection of gear engagement and bearings before final assembly; internal gears and bearings are not part of this item.
Performance note: although the cover does not change gear ratios, maintaining a sealed and correctly mounted housing helps protect gear engagement and extends component life, which is useful when running aggressive trail setups.
