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 5.7L Hemi engines. Designed to fit most Chrysler, Dodge, Jeep, and Ram models equipped with the 5.7L Hemi, this piston set offers a reliable upgrade for stroker engine builds and high-performance applications.

These pistons are crafted to accommodate a 3.795" stroke and a 6.125" rod length, making them ideal for 366 cubic inch stroker configurations. With a compact height of 1.21 inches and a -12cc dish top design, they provide precise combustion chamber volume control to optimize compression ratios and engine efficiency.

Key Features:

Built to meet the demands of high-performance small block Mopar Hemi engines, the DSS Racing FX Series pistons deliver strength, reliability, and compatibility with a variety of engine setups. Key features include:

• Forged construction for superior strength and durability under high stress
• Comp height of 1.21 inches for optimal piston-to-deck clearance
• 12cc dish top design to manage compression ratios effectively
• .927" wrist pin diameter with options for full-floating or press-fit pins
• Ring groove dimensions of 1.2mm / 1.2mm / 3mm for reliable ring sealing
• Designed for a 3.795" stroke and 6.125" connecting rod length
• Available with varying combustion chamber volumes to achieve compression ratios approximately 9.83:1, 8.98:1, or 8.15:1 depending on the piston dish size (65cc, 74cc, 85cc)
• Compatible with most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi Gen III engines

Construction & Design:

The DSS Racing FX Series pistons are manufactured from high-quality forged aluminum alloy, ensuring excellent strength-to-weight ratio and resistance to thermal and mechanical stress. The forging process enhances grain structure, providing improved fatigue resistance and durability compared to cast pistons.

The pistons feature a precision-machined dish top design with a -12cc volume to optimize combustion chamber shape and compression ratio. The wrist pin bore supports either full-floating or press-fit pins, allowing flexibility depending on engine build preferences. Ring grooves are engineered to accommodate standard 1.2mm top and second rings with a 3mm oil ring, ensuring effective sealing and oil control under demanding conditions.

Installation & Fitment:

This piston set is designed for direct fitment in most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi Gen III engines, particularly those undergoing stroker builds with a 3.795" stroke crankshaft and 6.125" connecting rods. Installation requires standard engine assembly procedures, and builders should verify clearances and compression ratios based on their specific cylinder head and block deck configurations.

Due to the forged construction and precise dimensions, these pistons are well-suited for high-performance rebuilds, stroker kits, and engine upgrades where reliability and strength are critical.

What's Included:

• Set of 8 forged pistons with -12cc dish tops
• Wrist pin bore compatible with .927" pins (pins not included)
• Ring grooves sized for 1.2/1.2/3mm piston rings (rings not included)

Ideal For:

This piston set is ideal for engine builders, performance enthusiasts, and professional shops upgrading or rebuilding Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines. It is particularly suited for stroker engine builds aiming to increase displacement to 366 cubic inches while maintaining reliable compression ratios and durability under high RPM and boost conditions.
