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 durable, high-performance pistons tailored for the Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines. Designed to accommodate stroker builds with a 3.795" stroke and 6.125" connecting rods, these pistons provide reliable strength and precision fitment for Gen III Hemi applications.

Ideal for both street and track use, this piston set enhances engine durability under increased power and stress, making it a solid choice for performance upgrades and rebuilds. The pistons feature a -12cc dish top design to optimize compression ratios depending on combustion chamber size, supporting a range of build preferences.

Key Features:

These forged pistons incorporate advanced design elements to ensure performance and longevity:

• Compatible with 5.7L Small Block Mopar Hemi Gen III engines
• FX Series forged construction for superior strength and durability
• Comp height of 1.21" for precise deck clearance
• 12cc dish top to optimize combustion chamber volume and compression ratio
• Pin diameter of .927" with options for full-floating or press-fit installation
• Ring groove dimensions: 1.2mm top and second rings, 3mm oil ring
• Designed for 3.795" stroke and 6.125" connecting rods
• Compression ratio options approximately ranging from 8.23 to 9.94 depending on combustion chamber size (65cc, 74cc, 85cc)
• Precision machining ensures consistent performance and fitment

Construction & Design:

Crafted from high-grade forged aluminum alloy, these pistons deliver exceptional strength-to-weight ratio, reducing reciprocating mass while withstanding the rigors of high-performance operation. The FX Series forging process enhances grain structure for improved fatigue resistance and thermal stability.

The pistons feature a carefully engineered dish top design with a -12cc volume to fine-tune compression ratios for various combustion chamber sizes, allowing builders to optimize power and efficiency. The pin bore supports either full-floating or press-fit wrist pins, providing flexibility based on engine build preferences.

Installation & Fitment:

These pistons are designed to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines, specifically the Small Block Mopar Hemi Gen III platform. Installation requires standard engine assembly procedures, with attention to ring end gap and piston-to-wall clearance to ensure optimal performance and longevity.

Builders should verify compatibility with their specific stroker kit and connecting rods, as the pistons are optimized for a 3.795" stroke and 6.125" rod length. Professional installation is recommended to maintain engine reliability and performance.

What's Included:

• Set of forged pistons (quantity varies per SKU)
• Wrist pin options for full-floating or press-fit installation
• Precision-machined ring grooves ready for standard piston rings

Ideal For:

This piston set is ideal for performance enthusiasts, engine builders, and professional shops upgrading or rebuilding 5.7L Hemi engines for increased displacement and power. Whether building a stroker motor for street performance, racing, or off-road applications, these pistons provide the strength and design features necessary for reliable, high-output operation.
