Whether upgrading for street performance, racing, or custom engine projects, these forged pistons provide a solid foundation for increased power and longevity.

Key Features:

Built with precision and performance in mind, the DSS Racing FX Series pistons include:

• Forged construction for superior strength and resistance to high-stress conditions
• Comp height of 1.21 inches optimized for stroker applications
• 1.5cc flat top design for efficient combustion and power delivery
• .927-inch pin diameter compatible with full-floating or press-fit wrist pins
• Ring groove dimensions of 1.2mm top and second rings, 3mm oil ring for effective sealing
• Designed for a 3.795-inch stroke and 6.125-inch connecting rods
• Available in multiple combustion chamber volumes (65cc, 74cc, 85cc) to tailor compression ratios from approximately 8.94:1 to 11.07:1
• Precision machining ensures consistent fitment and performance

Construction & Design:

Each piston in the DSS Racing FX Series set is forged from high-quality aluminum alloy, providing an excellent balance of lightweight design and structural integrity. The forging process enhances grain structure, resulting in pistons that withstand the rigors of high RPM and elevated cylinder pressures common in stroker builds.

The flat top piston crown with a -1.5cc volume optimizes combustion efficiency and helps control detonation. The pistons are engineered to fit the 5.7L Hemi Gen III small block architecture, ensuring precise compatibility with factory and aftermarket components. The ring grooves are carefully cut to accommodate performance ring sets, maintaining effective sealing and oil control under demanding conditions.

Installation & Fitment:

This piston set is designed to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines, particularly those utilizing the Gen III small block platform with a 3.795-inch stroke and 6.125-inch rods. Installation requires standard engine assembly procedures, and the pistons support both full-floating and press-fit wrist pin configurations to suit builder preference.

Proper ring end gap and piston-to-wall clearance should be verified during assembly to ensure optimal performance and longevity. These pistons are ideal for stroked 368 builds and can be integrated into a variety of performance engine combinations with minimal modification.

What's Included:

• Set of forged pistons (quantity as per kit selection)
• Compatible wrist pins (full-floating or press-fit depending on kit)
• Ring grooves pre-cut to specified dimensions

Ideal For:

This piston set is perfect for engine builders and performance enthusiasts upgrading or rebuilding Chrysler, Dodge, Jeep, or Ram 5.7L Hemi engines. It suits stroker builds aiming for increased displacement and power, including street performance, drag racing, and custom engine projects requiring durable, high-quality forged pistons.
