Improve XB2 Traction with the XRAY 325002 Upgrade

The XRAY 325002 Adjustable Ball Differential is a solid upgrade aimed at XB2 drivers wanting better control on low to medium traction surfaces. Constructed from Hudy Spring Steel, the diff is built to withstand racing demands while allowing external tuning to dial in balance on dirt and clay layouts.

Smooth Operation with Hardened Components

This differential set includes carbide thrust bearings and carbide balls to ensure low-friction rotation. Outdrive adapters are supplied for compatibility with 2.5mm pin drive shafts, making swap-ins straightforward. The hardened steel parts improve durability and reduce the frequency of component replacement after heavy use.

For XB2 racers focusing on consistent traction and lower maintenance, this adjustable ball differential is a reliable upgrade that sharpens handling on loose and medium-grip surfaces.
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.

Will changing to this diff alter corner entry or exit more?

Adjusting preload and torque bias can influence both entry and exit behaviour; riders often tune for a bit more lock to improve drive out of corners on dirt.

Are replacement carbide balls available separately?

Yes, individual replacement carbide balls and thrust bearings are commonly available from parts suppliers so you can service the diff without replacing the whole unit.

How often should I check the diff after racing?

Inspect the diff after each hard session for debris and wear, clean and relubricate as needed to maintain smooth performance and prevent premature wear.
