D.S.S. FX-Series Forged Piston and Ring Kits

Pushing the envelope on your engine combination? Need parts that will stand up to the demands of today's power levels? DSS FX Series piston and ring kits increase your horsepower potential without killing the budget. Forged and machined with your choice of premium aircraft quality 4032 or 2618 alloy, these kits are a great choice for naturally aspirated, nitrous, or boosted engines with the added strength from the internal gussets. Additional CNC milling removes material in non-critical areas to achieve a lighter weight for the perfect balance of strength, power, and longevity. Kit includes a DSS XP piston ring set featuring gas nitrided steel top rings, Napier second rings, and flex vent oil rings.

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:

* 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
