Serpent 500646 - SRX2 4-Gear Transmission Kit - Precision Low-Traction Upgrade  [SER500646]

Fine-Tuning SRX2 Handling with a 4-Gear Setup

The Serpent 500646 - SRX2 4-Gear Transmission Kit is a practical upgrade for SRX2 owners who want improved control on low to medium grip tracks. It replaces the standard 3-gear arrangement and lets drivers smooth out power delivery for more consistent lap times.

Complete Gearbox Package

The kit includes a precision-machined aluminum motor plate, rugged transmission cases, idler shafts, gears, bearings, and all necessary hardware. The standing 4-gear layout produces a more forgiving driving feel compared to aggressive 3-gear setups, making it easier to manage traction in variable conditions.

Chassis Fit and Configuration Options

Engineered to mount cleanly on both aluminum and carbon chassis plates, the 4-gear unit supports straightforward changes between standing and laydown configurations. That adaptability allows quick tuning for different surfaces and racing styles.
