DSS FX Piston is a 2618 material. These pistons include valve reliefs for both PI and TrickFlow heads. The FX pistons have a proven X groove on the skirt to control oiling. 

 


FX series pistons feature the patented X Groove skirt design which reduces damage caused by fuel wash down and break-in debris for superior skirt, cylinder, and ring life. For stroker engines, the advanced skirt design improves piston stability and ring seal which provides quieter operation. Features include:

* Pin lock ring removal slot
* Precision honed piston pin bores
* High strength piston wrist pins
* Deep CNC valve reliefs
