Serpent 500646 - SRX2 4-Gear Transmission Kit - Tunable Low-Grip Setup  [SER500646]

How the 4-Gear Unit Changes SRX2 Behaviour

The Serpent 500646 - SRX2 4-Gear Transmission Kit offers an alternative to the factory 3-gear system, aimed at improving predictability on low to medium traction tracks. It helps pilots reduce abrupt reactions and makes the car more consistent lap to lap.

All-Inclusive Transmission Components

This package supplies a machined aluminium motor plate, sturdy transmission cases, idler shafts, gears, bearings and the full complement of fasteners. The standing 4-gear arrangement tends to soften the car's response compared with direct 3-gear setups, which many drivers find easier to handle during a race weekend.

Fits Multiple Chassis Types and Layouts

Designed for use with both aluminium and carbon chassis plates, the 4-gear transmission lets you switch between standing and laydown orientations without major mods. That flexibility allows straightforward tuning to suit different track grip and driving techniques.
