Precision Pistons for Classic XB Chassis

The XRAY 358037 4-Hole Composite Shock Piston Set is manufactured to ensure precise roundness and reliable piston travel inside vintage XB shocks. Consistent geometry reduces stick-slip and delivers smoother stroke behaviour under load.

Flow-Optimised Four Hole Design

Each piston has four straight ports and comes in 1.3mm, 1.4mm and 1.5mm sizes to offer a clear step in flow rates. The design supports using heavier oils without sacrificing responsiveness, widening your tuning range for different driving styles.

Applications and Compatibility Notes

These wide pistons are a direct upgrade for older XRAY XB series models. They are suitable for restoration work and for drivers seeking more controllable damping without altering shock geometry.
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 I use these pistons with my current shock oil?

Yes, but expect different feel; try a heavier oil grade after fitting to take advantage of the larger flow capacity.

Do the pistons require special installation tools?

No special tools are required beyond standard shock rebuild tools and a clean workspace to avoid contaminating the oil.

Will these affect handling on rough surfaces?

They can improve control over rough terrain by allowing thicker oils and gentler stroke damping, which helps absorb repeated impacts.
