Upgrade Your XRAY Vintage XB Suspension

Built for hobbyists who demand smoother response, the XRAY 358037 4-Hole Composite Shock Piston Set offers precise manufacturing to ensure roundness and reliable motion inside vintage XB shock bodies. The quality control in production helps reduce stiction and keeps piston action consistent lap after lap.

Better Oil Flow and Damping Range

The pistons use four straight ports and are supplied in 1.3mm, 1.4mm and 1.5mm sizes. Compared with fewer-hole designs, this layout permits higher oil throughput so you can run thicker shock oil and expand your damping options to suit track or club conditions.

Fitment and Practical Use

These wide pistons are made to work with older XRAY XB series models, providing an easy upgrade for riders restoring classics or tuning for local racing. They give predictable damping behaviour without altering the original 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.

Which XRAY XB versions accept these pistons?

They are intended for older XRAY XB series shock assemblies; check your shock body internal diameter and shaft compatibility before fitting.

How do I choose between 1.3mm, 1.4mm and 1.5mm holes?

Start with the middle size and adjust based on response: smaller holes give firmer damping, larger holes allow thicker oil and softer feel.

Any maintenance tips after installation?

Inspect pistons for debris when you open shocks, use clean oil and check piston roundness during rebuilds to maintain smooth action.
