Refine Handling with XRAY 4-Hole Shock Pistons

The XRAY 358037 4-Hole Composite Shock Piston Set is produced with careful tolerances to preserve roundness and smooth movement inside period XB shock absorbers. That consistency helps deliver repeatable damper response during tuning and track sessions.

Greater Oil Throughput for Tuned Damping

The pistons feature four straight holes and are offered in 1.3mm, 1.4mm and 1.5mm options to vary flow. This configuration increases oil throughput compared with lower-hole pistons and makes it easier to use thicker oils for a wider damping spectrum.

Compatibility and Use Cases

Designed for older XRAY XB series cars, these wide pistons are ideal for restorations, club racing or anyone wanting to refine handling while retaining original shock hardware. They do not alter shock travel or mounting points.
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 these pistons fit stock XB shock bodies?

They are intended for older stock XB shock bodies; confirm your shock internal diameter matches the piston fit before ordering.

Which hole size is best for on-road tuning?

For on-road use, many start with 1.4mm for balanced response, then test 1.3mm for firmer damping or 1.5mm for a softer, higher-flow setup.

Any tips for achieving consistent damping?

Use fresh, filtered shock oil, ensure pistons are clean and aligned, and remove trapped air while assembling to get repeatable damper behaviour.
