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, this piston set supports stroker builds with a 3.795" stroke and is ideal for those upgrading their engine internals for increased power and reliability.

These pistons feature a compact design with a -12cc dish top and a compression height of 1.21", allowing for precise control over compression ratios depending on combustion chamber volume. Whether you are building a street performance engine or a more aggressive stroker setup, these forged pistons provide the strength and consistency required for demanding applications.

Key Features:

Crafted with precision and performance in mind, the DSS Racing FX Series Forged Pistons offer the following key features:

• Compatible with 370 Small Block Mopar Hemi Gen III engines
• Forged construction for superior strength and durability under high stress
• Compact piston design with a -12cc dish top for optimized combustion
• Compression height of 1.21" to suit stroker configurations
• Pin diameter of .927" with options for full-floating or press-fit pins
• Ring groove dimensions of 1.2/1.2/3 mm for reliable sealing and reduced friction
• Designed for a 3.795" stroke and 6.125" connecting rods
• Approximate compression ratios vary by combustion chamber size: 65cc-9.91, 74cc-9.07, 85cc-8.22
• Precision engineered to maintain tight tolerances for consistent engine performance

Construction & Design:

Each piston in this set is forged from high-grade aluminum alloy, providing an excellent balance of lightweight strength and thermal conductivity. The forged design ensures enhanced resistance to cracking and deformation under extreme combustion pressures and temperatures common in performance and stroker engines.

The pistons feature a carefully engineered dish top with a -12cc volume to optimize combustion chamber dynamics and control compression ratios across different chamber sizes. The pin bosses are designed to accommodate either full-floating or press-fit wrist pins, giving builders flexibility based on their engine setup preferences.

Installation & Fitment:

This piston set is designed to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines equipped with the Gen III small block Mopar Hemi platform. Installation requires standard engine assembly procedures, and builders should verify compatibility with their specific stroker crankshaft and rod combination. The pistons are compatible with a 3.795" stroke and 6.125" connecting rods, making them ideal for stroker builds aiming to increase displacement and power output.

Proper ring installation and piston orientation are critical for optimal performance and longevity. It is recommended to follow DSS Racing’s installation guidelines and consult with a professional engine builder if unsure about fitment or assembly steps.

What’s Included

• Set of forged pistons (quantity as per engine requirements)
• Wrist pin options (full-floating or press-fit depending on SKU)
• Ring grooves pre-machined for 1.2/1.2/3 mm piston rings

Ideal For:

This piston set is ideal for automotive enthusiasts, engine builders, and performance shops upgrading or rebuilding 5.7L Hemi engines with stroker configurations. Whether you are building a high-performance street engine, a weekend racer, or a reliable stroker for daily driving, these forged pistons provide the strength and precision needed to handle increased power and boost levels.
