XRAY 323018 LCG Composite Rear Gearbox for XB2 - Low CG Upgrade  [XR-323018]

Precision rear gearbox engineered for track use

The XRAY 323018 LCG Composite Rear Gearbox fits rear motor XB2 builds and is moulded from high-quality composite to deliver an ultra-low center of gravity that improves stability and consistency. The design gives straightforward access to the differential so racers can make quick adjustments between runs.

Slim layout to boost rear traction

This gearbox uses a super-narrow profile to cut weight and move components closer to the chassis centerline. By shifting motor and top shaft mass nearer the rear axle, it helps the car find more traction on low-grip surfaces and improves rear-end bite.

Adjustable differential height with six settings

The XRAY 323018 provides six differential height positions using the supplied eccentric bushings, allowing fine tuning for track conditions, ride height and tyre choice.

Built for integration and easy servicing

Besides housing the transmission, the unit acts as the mounting point for the rear roll center holder, motor plate and rear shock tower. Robust construction keeps components secure while allowing straightforward access for maintenance and upgrades.

For racers aiming to improve stability and traction on low-grip tracks, the XRAY 323018 gearbox is a practical, durable upgrade for the XB2 series.
