Precision Traction Upgrade for XB808 - XRAY 355102

The XRAY 355102 Active Differential is crafted to enhance XB808 forward traction and stability under throttle, improving mid-corner and exit performance. Its internal mechanism engages on-power to provide a steadier and more controllable driving feel.

Refined On-Power Behaviour for Racing

Drivers seeking a reliable and tunable setup will appreciate the diff's adjustable character. It is designed to be tuned for different on- and off-power responses using segmented internals and optional gear choices.

Technical Highlights

Specifications

  • Compatibility: Compatible with XRAY XB808 models
  • Gear Type: Adjustable Active Differential
  • Tooth Count: 43T
  • Material: HUDY Spring Steel and Composite
  • Optional Gears: Available in 38T and 120° segment

Quality Components and Accurate Manufacture

Lightweight Composite Diff Body: The special composite body resists dimensional change from heat and is finished for excellent roundness, with an integrated hard steel outdrive ring for stability.

Durable Diff Outdrives: Outdrives are precision CNC-machined from HUDY Spring Steel, heat-treated and lightened to balance strength with smooth operation.

High-Quality Internal Gears: Hardened die-cast steel gears make up a rugged internal set designed for longevity and dependable performance.

Precision Diff Gear: The machined 43T gear is tested for exact fit and can be exchanged for the optional 38T to alter engagement characteristics.

Adjustable Diff Segments: CNC-machined steel segments include finely cut grooves for straightforward adjustment; change the standard 90° segment for a 120° option to vary on/off-power lock behaviour.

For XB808 owners looking to refine handling and increase traction on throttle, the XRAY 355102 Active Differential is a precise, tunable upgrade.

Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.
It mainly affects on-power behaviour and corner exit traction; steering at low speed may feel similar but mid to high speed balance will be more consistent.
Yes, the internal gears, segments and outdrives are serviceable and replaceable, allowing long term upkeep and tuning without replacing the whole unit.
The 43T provides the standard engagement balance for general track use; switching to 38T alters the gearing relationship and can change how the diff transfers torque under load.
Rebuild the diff with the recommended fitment procedures, check gear mesh and runout, then test with small incremental changes to segment angle or gear choice to find your preferred balance.
