Product Description
FX Pistons: Are you pushing the limits of your engine combination and need components that can handle today’s high power levels? DSS Racing’s FX Series pistons are engineered to maximize horsepower potential without exceeding your budget.Forged and machined in the U.S.A. from your choice of premium aircraft-quality 4032 or 2618 alloy, FX pistons are ideal for naturally aspirated, nitrous, or boosted combinations. They feature the patented X Groove Skirt design, which reduces damage from fuel washdown and break-in debris, prolonging skirt, cylinder, and ring life. Thinner ring grooves maximize ring land width and reduce radial groove depth, drastically improving piston strength in the vulnerable ring land area.FX pistons incorporate advanced ring land features, enhancing the effectiveness of modern piston ring technology. These include low-volume top land contact reduction grooves, a second land pressure accumulator groove, a third land oil accumulator, and a skirt top oil accumulator that works in conjunction with drain backs and the X Groove. The advanced, stroker-friendly skirt design improves piston stability, enhances ring seal, and provides quieter operation.DSS F-style 4032 and 2618 alloy forgings with internal gusseting deliver superior strength without excessive weight. Additional CNC milling removes material from non-critical areas, achieving a lighter weight for the perfect balance of strength, power, and longevity.Other features include forced pin oiling, drilled bottom land intersecting oil groove drain backs, a pin lock ring removal slot, precision-honed piston pin bores, diamond-turned high-strength skirts, and high-precision, high-strength piston pins. Deep CNC valve reliefs accommodate more aggressive cam and cylinder head combinations, paving the way for significant power increases.FX pistons are commonly used in V8 applications ranging from 450 to 1,500+ horsepower, depending on the application.
