Serpent 903806 Front Oneway Differential S9XX Track Edition  [SER903806]

Precision Front Upgrade for S9XX

The Serpent 903806 Oneway Differential Front is aimed at S9XX racers who want a sharper front response on tighter circuits. It swaps in for the original front axle and combines the braking traits of a differential with a one-way exit drive. Forged from magnesium alloy and weighing 22 grams, it keeps the front end light and responsive.

Tune Front Bite and Exit Drive

This unit delivers crisper turn-in and predictable exits; drivers can tune behaviour by changing the internal oil viscosity. Lighter oil softens front bite for high-grip drives, while heavier oil increases braking on slick surfaces.

For competitors wanting a compact, tunable front diff, the Serpent 903806 provides an effective way to refine handling and corner exits without adding weight.
