The XRAY 358031 Delrin 2-Way Flow Shock Pistons are engineered for riders who want predictable suspension under load. Included pistons have eight 1.3mm holes and two 1.2mm holes so you can tune oil flow for a range of surfaces.
These pistons use a rubber valve to close two holes on upward travel, while all ten holes open on the downward stroke. That asymmetric flow profile helps cushion landings and reduces pogo on rough terrain.
Manufactured from a durable Delrin composite and precision moulded, the pistons maintain roundness and run smoothly inside shock bodies. The consistent geometry helps ensure identical damping across each corner.
