Serpent 804367 SL6 XLI Race-Focused 2-Speed Gearbox  [SER804367]

Performance Launches from the SL6 XLI Design

The Serpent 804367 SL6 XLI 2-speed gearbox kit focuses on cutting rotating mass to give quicker launches for Serpent Natrix 748 and 747 cars. Michael Salven's XLI approach reduces inertia so drivers get improved initial acceleration without altering the proven 2-speed gearing.

Slimmed Parts for Faster Response

Components including the adaptor, shoes, and bell have reduced size and mass, which lowers overall inertia. The result is sharper throttle response while the established 2-speed gearset maintains reliable shifting behavior.

Compatible Fit for Existing SL6 Cars

Owners of the Natrix 748 and 747 can fit the SL6 XLI with minimal modification, enabling a practical upgrade route for racers who want better acceleration without an extensive rebuild.
