Serpent 402003 Magnesium Differential Housing - Precision Racing Part  [SER402003]

Lightweight Magnesium Differential Case for Racing

The Serpent 402003 Magnesium Gear Differential Housing delivers reduced mass with precise machining for touring car drivetrains. Constructed from magnesium, it helps lower rotating weight while maintaining the rigidity required for reliable gear engagement. The result is smoother drivetrain behaviour under sustained running.

Why Magnesium Works in RC Gearboxes

Magnesium provides a favourable strength-to-weight balance that benefits acceleration and reduces inertial load on the drivetrain. Its stiffness supports accurate gear alignment, helping to limit wear and maintain consistent performance during competitive use.

Designed for Dependable Track Use

For model racers who demand predictable handling, the Serpent 402003 offers an upgrade path that focuses on durability and reduced internal friction. Regular inspection and proper setup will help the housing perform well across events and practice sessions.
