XRAY 355102 XB808 Active Diff Race Upgrade 43T  [XR-355102]

XRAY 355102 Active Diff - XB808 Traction Upgrade

The XRAY 355102 Active Differential is a performance-driven upgrade for the XB808 that enhances forward bite and stability when on-throttle. Its engaging internal geometry helps maintain momentum and control on loose or grippy surfaces.

Better Forward Grip and Stability

Drivers of all abilities benefit from the more predictable throttle behaviour this diff provides. The adjustable internals allow tuning for both on- and off-power conditions to suit track grip and driving preference.

Technical Highlights

Robust Materials and Accurate Fitment

Lightweight Composite Diff Body: The composite body resists expansion from heat and is precision-finished to keep the diff round and true, including a hardened steel outdrive ring for longevity.

Durable Diff Outdrives: Outdrives are CNC-machined from HUDY Spring Steel, lightened and hardened to provide reliable strength and smooth meshing with the internal gears.

High-Quality Internal Gears: Die-cast, hardened steel gears give durable performance and long life under racing loads.

Precision Diff Gear: Each gear is machined and checked for exact fit; the standard 43T gear is laser marked and can be replaced by the optional 38T for different behaviour.

Adjustable Diff Segments: CNC-machined steel segments feature cleanly cut grooves for quick fine-tuning; swapping the stock 90° segment for a 120° option alters on/off power characteristics.

The XRAY 355102 Active Differential is an effective upgrade for XB808 owners wanting a more controllable and faster-feeling buggy through improved traction management.
