XRay 2-Way Delrin Shock Pistons 1.3/1.1mm (2) XR358028

The XRay 2-Way Flow Delrin Shock Piston set (XR358028) provides precision composite-moulded pistons for two shock absorbers, each configured with six 1.3mm holes and two 1.1mm holes. Manufactured from a specially formulated composite for smooth action and durability, the proven moulding process ensures perfectly round pistons that glide inside the shock bodies for consistent, repeatable damping.

How The 2-Way Flow Works

With the rubber valve installed on the piston, two holes are closed when the piston travels up. When the piston travels down, the valve opens to add two extra flow paths, allowing oil to pass through eight holes in total. This setup supports soft shock settings while delivering controlled damping and stable landings from jumps.
