Overview

The DSS Racing FX-Series forged pistons are crafted from premium aircraft-quality 2618 alloy to increase horsepower potential for naturally aspirated, nitrous, or boosted engines. These pistons feature a dish style with two valve reliefs and a +10.00cc volume, designed for a 3.898 in. bore and a 3.900 in. stroke.

They utilize a patented X-Groove skirt design that reduces damage from fuel wash down and break-in debris, improving skirt, cylinder, and ring life. For stroker engines, the advanced skirt design enhances piston stability and ring seal for quieter operation. Each piston has precision-honed pin bores and includes high-strength wrist pins and retainers, suitable for press-fit or floating wrist pin styles.
