Tune the XB808 with the XRAY 355102 Active Diff
The XRAY 355102 Active Differential is engineered to sharpen XB808 throttle response and corner exits by engaging on-power to increase forward traction. It gives drivers consistent behaviour when accelerating out of turns on a range of surfaces.
Designed for Controlled Throttle Response
Suitable for racers who want predictable handling and for hobbyists seeking easier control, this diff lets you dial in both on- and off-power traits. Fine adjustments are possible thanks to the internal segmented design and optional gears.

Engineered Parts for Consistent Performance
Lightweight Composite Diff Body: The composite shell is built to resist thermal growth and maintains roundness for reliable diff operation, including a molded steel outdrive ring for strength.
Durable Diff Outdrives: HUDY Spring Steel outdrives are CNC-machined, lightened and hardened to reduce wear and maintain smooth rotation inside the diff body.
High-Quality Internal Gears: Hardened die-cast steel gears form a durable internal set that stands up to race use while keeping wear low.
Precision Diff Gear: Machined and inspected for correct fit, the standard 43T gear provides precise engagement and can be swapped to the 38T option for different response.
Adjustable Diff Segments: CNC-machined steel segments have accurate grooves for adjustment; swap the stock 90° segment for an optional 120° unit to shift on- and off-power characteristics.
For XB808 users wanting better traction control and smoother handling, the XRAY 355102 Active Differential is a reliable upgrade that supports race setup tuning.
