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 for their Chrysler, Dodge, Jeep, or Ram 5.7L Hemi engines. Designed specifically for the Gen III 5.7L Hemi platform, these pistons accommodate stroker builds with a 3.795" stroke, delivering reliable strength and improved combustion efficiency.

Ideal for high-performance street and race applications, this piston set offers a perfect balance of lightweight construction and robust design, helping to maximize power output while maintaining engine longevity under demanding conditions.

Key Features:

These forged pistons incorporate advanced engineering to meet the rigorous demands of stroker small block Mopar Hemi builds. Key features include:

• Compatible with 366 Small Block Mopar Hemi Gen III engines
• FX Series forged construction for superior strength and durability
• Compression height of 1.21" for optimal piston-to-deck clearance
• +9cc dome top design to enhance combustion chamber efficiency
• .927" pin diameter with options for full-floating or press-fit pins
• Ring groove dimensions of 1.2mm / 1.2mm / 3mm for reliable sealing
• Designed for a 3.795" stroke and 6.125" connecting rods
• Available in multiple combustion chamber volumes to tailor compression ratios (65cc, 74cc, 85cc)
• Approximate compression ratios ranging from 9.94:1 to 12.73:1 depending on dome volume

Construction & Design:

Crafted from high-grade forged aluminum alloy, these pistons are engineered to withstand the increased stresses of stroker configurations and high-performance operation. The FX Series forging process ensures exceptional tensile strength and resistance to thermal expansion, reducing the risk of piston failure under extreme conditions.

The dome top design with a +9cc volume enhances combustion efficiency by promoting better flame propagation and higher compression ratios. Precision-machined pin bores accommodate either full-floating or press-fit wrist pins, providing flexibility for different engine builds and preferences.

Installation & Fitment:

This piston set is designed to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines equipped with Gen III small block configurations. Installation requires standard engine assembly procedures and may involve custom clearancing depending on the specific stroker kit and cylinder head combination used.

Builders should verify rod length and stroke compatibility, as these pistons are optimized for a 3.795" stroke and 6.125" connecting rods. Proper ring installation and torque specifications should be followed to ensure reliable sealing and performance.

What's Included:

• Set of forged pistons (quantity as required for engine configuration)
• Wrist pin options: full-floating or press-fit (depending on selection)
• Ring grooves machined to 1.2/1.2/3mm specifications

Ideal For:

This piston set is perfect for performance enthusiasts, engine builders, and racers upgrading their 5.7L Hemi engines with stroker kits. Whether building a high-output street machine or a dedicated race engine, these pistons provide the strength and precision needed to handle increased displacement and power levels while maintaining reliability.
