Overview:

The DSS Racing 5.7 Stroker Small Block Mopar Hemi Gen III FX Series Forged Piston Set is engineered specifically for high-performance applications in Chrysler, Dodge, Jeep, and Ram vehicles equipped with the 5.7L Hemi engine. Designed to accommodate stroker builds with a 3.795" stroke and 6.125" rod length, these pistons provide enhanced durability and reliability under increased power demands. Ideal for enthusiasts and professional builders seeking to upgrade their engine’s strength and efficiency, this piston set supports a range of compression ratios to suit various tuning goals.

Whether you are building a street performance engine or a race-ready powerplant, these forged pistons offer the precision and toughness required to withstand high RPMs and boost pressures. Their compatibility with most 5.7L Hemi Gen III engines ensures a straightforward upgrade path without extensive modifications.

Key Features:

Designed with advanced engineering and quality materials, the DSS Racing FX Series pistons deliver exceptional performance benefits:

• Forged construction for superior strength and durability compared to cast pistons
• Comp height of 1.21" optimized for stroker configurations
• 1.5cc flat top design to fine-tune compression ratios
• .927" wrist pin diameter with options for full-floating or press-fit installation
• Ring groove dimensions of 1.2mm/1.2mm/3mm for reliable ring sealing and reduced friction
• Compatible with 3.795" stroke crankshafts and 6.125" connecting rods
• Available in multiple combustion chamber volume options: 65cc (11.1:1), 74cc (10.03:1), and 85cc (8.97:1) for flexible tuning
• Precision machining ensures excellent balance and fitment within the Gen III Hemi block

Construction & Design:

Each piston in the DSS Racing FX Series set is crafted from high-grade forged aluminum alloy, providing a lightweight yet incredibly strong component capable of handling the stresses of high-performance engines. The forging process enhances the metal’s grain structure, improving fatigue resistance and thermal conductivity. The flat top design with a slight dish (-1.5cc) allows for precise control over compression ratios, essential for optimizing combustion efficiency and power output.

The pistons feature carefully engineered ring grooves that maintain ring stability and reduce blow-by, while the wrist pin bore is designed to accept either full-floating or press-fit pins, depending on your build preference. This versatility ensures compatibility with a wide range of engine assembly techniques and performance goals.

Installation & Fitment:

This piston set is designed to fit most Chrysler, Dodge, Jeep, and Ram vehicles equipped with the 5.7L Hemi Gen III engine. Installation requires standard engine assembly procedures, with attention to proper ring end gap and piston-to-wall clearance based on your specific stroker build. The pistons accommodate a 3.795" stroke crankshaft and 6.125" connecting rods, making them ideal for stroker engine configurations.

While these pistons are engineered for direct fitment, professional installation is recommended to ensure optimal performance and longevity. No major block modifications are typically necessary, but verification of clearances and compatibility with your existing components is advised.

What's Included:

• Set of forged pistons (quantity as required for your engine configuration)
• Wrist pins compatible with full-floating or press-fit installation
• Ring sets with 1.2mm top and second rings and 3mm oil control rings
