Race-Tuned XRAY 358029 Delrin Pistons for Controlled Damping

Made for serious hobby drivers, the XRAY 358029 Delrin Shock Pistons employ a two-way flow system that responds to both rebound and compression demands. The pistons incorporate six 1.4mm holes and two 1.1mm holes to regulate oil movement in both directions.

How the Two-Way Flow Works

This arrangement delivers different damping when the piston travels up versus down. During upward travel a rubber valve covers two openings to maintain pressure; during downward travel the valve exposes additional openings so oil can move through all eight holes. The result is improved landing control and better behaviour on uneven terrain.

Long-Life Composite Design

Produced from a carefully selected composite, these pistons maintain shape and roundness for reliable action inside shock bodies. Consistent manufacturing tolerances help ensure matching performance across all four corners, making setup changes more predictable.
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 swap these into my existing shocks?

In most cases these pistons fit XRAY shock assemblies. Verify internal dimensions and seal condition to confirm compatibility before fitting.

What benefits do the extra holes provide?

The mix of 1.4mm and 1.1mm holes lets you control flow rates for different travel directions, giving tuners more options to dial in landing stability and midstroke control.

How should I maintain these pistons?

Keep pistons and shock bodies clean and inspect for wear. Replace torn seals and refresh oil regularly to preserve consistent damping performance.

Should I change springs when using these pistons?

Spring choice affects overall ride height and response. Use spring rate tweaks alongside oil weight changes to achieve the balance you want for jumps and rough sections.
