D.S.S. FX-Series Forged Piston and Ring Kits
5 Customer Reviews
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.

* Forced pin oiling
* Drilled bottom land intersecting oil groove drain backs
* Pin lock ring removal slot
* Precision honed piston pin bores
* High-strength piston wrist pins
* Deep CNC valve reliefs
