Serpent 804367 SL6 XLI Performance 2-Speed Gearbox Kit  [SER804367]

Performance Tuning with Serpent 804367 SL6 XLI

The Serpent 804367 SL6 XLI 2-speed gearbox kit reduces rotating mass to enhance initial acceleration on Serpent Natrix 748 and 747 cars. Michael Salven's XLI concept targets lower inertia to improve launch and mid-range response while keeping the established 2-speed gearset.

Engineered Reduction in Rotating Mass

The design pares down components such as the adaptor, shoes, and bell to cut inertia and improve responsiveness. Those changes support quicker power delivery from the same gear ratios used on standard SL6 transmissions.

Practical Upgrade Path for Natrix Users

Fitting the SL6 XLI to Natrix 748 and 747 models is a practical upgrade that avoids major rewiring or chassis surgery. It suits tuners who want measurable gains in acceleration with minimal installation complexity.
