Fine tuning centre traction on the XB808 with XRAY 355103

The XRAY 355103 XB808 Adjustable Active Center Differential adds selectable centre behaviour to the XB808 chassis, helping drivers control traction transfer through corners. Its internal design focuses on predictable engagement and stable performance across sessions.

Thermally stable housing and refined outdrives

Constructed from XRAY composite for temperature stability, the diff body resists expansion under load. The integrated steel diff outdrive ring gives a consistent seating surface and the HUDY toughened steel outdrives are CNC-turned and lightened to lower inertia while preserving toughness.

Serviceable geartrain marked Active 42T

The internal gears are die-cast from premium steel and hardened to reduce wear. The HUDY steel diff gear is produced to tight tolerances and carries a laser-engraved Active 42T label for quick recognition, with 41T and 43T alternatives available.

Segment choice for tailored engagement

Active Diff segments are machined from robust steel and feature accurately cut V ramp grooves to control how the diff locks. The standard 90 degree segment is provided, with an optional 120 degree segment used for smoother gradual engagement.
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.

Can this centre diff be fitted without chassis mods?

Yes, it is designed to fit the XB808 centre location without additional chassis alterations when installed per the manufacturer guidance.

What setup changes pair well with this diff?

Try combining different segment angles with 41T-43T gear choices and diff oil weights to tune rotation and exit traction for your driving style and track surface.

Is special grease required for the internals?

No special grease is mandatory, but use a suitable diff lubricant and keep the internals free of dirt. Regular cleaning and inspection will extend service life.

How do I check for wear on the outdrives?

Remove the diff and inspect the outdrive flats and gear teeth for scoring or play. Replace any components showing significant wear to maintain smooth operation.

Are replacement segments and gears available?

Replacement Active Diff segments and 41T/42T/43T gear options are available from authorised parts sources to allow ongoing setup changes and repairs.
