Quick Acceleration with Serpent 804367 SL6 XLI

The Serpent 804367 SL6 XLI 2-speed gearbox kit is a targeted upgrade for RC racers wanting crisper throttle response. Designed by Michael Salven, this gearbox reduces rotating mass to improve acceleration on Serpent Natrix 748 and 747 chassis. XLI stands for "eXtra Low Inertia" and emphasises the reduction of inertial weight.

Lightweight Components for Snappier Launches

The SL6 XLI trims mass in parts like the adaptor, shoes, and bell to lower inertia. That lighter package helps cars get on the power quicker while keeping the proven 2-speed gears unchanged for reliable shifts.

Simple Fit for Natrix 748 and 747

Installing the SL6 XLI on Serpent Natrix 748 and 747 is straightforward and requires minimal chassis changes. This makes it a practical option for drivers who want faster acceleration without a major rebuild.

Installation typically uses the existing mounting points and standard setup parts; check gear mesh and driveline alignment but no unique shims are normally required.
Since the 2-speed gearset is unchanged, top speed remains governed by your ratios and motor; the XLI focuses on reducing inertia to improve acceleration and throttle response.
Yes, the gearbox uses established 2-speed components for reliability; lighter parts still require normal maintenance and correct setup to perform well in club racing.
