Overview:

The DSS Racing 5.7 Stroker Small Block Mopar Hemi Gen III FX Series Forged Piston Set is engineered for enthusiasts and builders seeking enhanced durability and performance in their 5.7L Hemi engines. Designed to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi models, these pistons are ideal for stroker builds and high-performance applications. With a focus on strength and precision, this piston set supports increased stroke and compression ratios, making it a reliable upgrade for street, strip, or off-road use.

Whether you are rebuilding your engine or upgrading for more power, the DSS Racing forged pistons provide the foundation for improved combustion efficiency and engine longevity under demanding conditions.

Key Features:

This piston set incorporates advanced design and manufacturing techniques to deliver superior performance and reliability:

• Forged construction for maximum strength and durability
• Comp height of 1.21 inches optimized for stroker applications
• 1.5cc flat top design to support various compression ratios
• .927-inch wrist pin diameter with options for full-floating or press-fit pins
• Precision ring grooves sized at 1.2mm / 1.2mm / 3mm for optimal sealing
• Compatible with 3.795-inch stroke crankshafts and 6.125-inch connecting rods
• Available in multiple combustion chamber volumes to tailor compression ratio: 65cc (11.18:1), 74cc (10.09:1), and 85cc (9.04:1)
• Designed specifically for the Gen III FX series 5.7L Hemi small block stroker engines

Construction & Design:

DSS Racing pistons are crafted from high-grade forged aluminum alloy, providing an excellent balance of lightweight strength and thermal conductivity. The forging process enhances grain structure, resulting in pistons that resist cracking and deformation under extreme heat and pressure. The flat-top design with a slight dish (-1.5cc) optimizes combustion chamber dynamics for improved power and efficiency.

The pistons feature precision-machined ring grooves to ensure proper ring seating and reduced blow-by, while the wrist pin bore accommodates either full-floating or press-fit pins, allowing flexibility depending on engine build preferences. The design supports increased stroke length and rod size, making it ideal for stroker engine configurations.

Installation & Fitment:

This piston set is engineered to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines equipped with Gen III FX series small block configurations. Installation requires standard engine rebuild procedures, including careful measurement of clearances and ring end gaps. Depending on your build, you may need to verify compatibility with your crankshaft stroke and connecting rod length to ensure proper piston-to-valve and piston-to-cylinder wall clearances.

Professional installation is recommended to maximize performance and reliability. These pistons are suitable for both full engine rebuilds and performance upgrades where increased stroke and compression ratios are desired.

What's Included:

• Set of 8 DSS Racing forged pistons
• Wrist pins (full-floating or press-fit options depending on SKU)
• Snap rings for wrist pin retention
• Detailed specifications and installation guidelines

Ideal For:

This piston set is perfect for engine builders, performance enthusiasts, and racers who want to upgrade their 5.7L Hemi engines for increased displacement and power. It suits stroker engine builds, high-compression applications, and those seeking enhanced durability under high RPM and boost conditions. Whether building a street performance vehicle, off-road rig, or race car, these pistons provide a solid foundation for reliable power gains.
