Overview:

The DSS Racing 6.1 Stroker Gen III Hemi Forged Piston Set is engineered specifically for Chrysler, Dodge, Jeep, and Ram 6.1L SRT8 engines. Designed to accommodate the 373 cubic inch small block Mopar Hemi Gen III stroker build, these pistons provide a reliable upgrade for enthusiasts seeking enhanced durability and performance. Ideal for high-performance street and race applications, this piston set supports increased stroke and compression ratios while maintaining OEM fitment standards.

Built to withstand the rigors of boosted and naturally aspirated powerplants, these forged pistons offer superior strength and thermal resistance compared to stock cast pistons. They are perfect for engine builders and performance tuners looking to maximize the potential of the 6.1L Hemi platform.

Key Features:

These pistons incorporate advanced design elements and precision manufacturing to deliver consistent performance and longevity:

• Compatible with 373ci Small Block Mopar Hemi Gen III stroker engines
• Forged construction for enhanced strength and durability
• Compensated dome top with +4cc volume for optimized combustion
• Pin diameter of .927" with options for full-floating or press-fit configurations
• Ring groove dimensions: 1.2mm top and second rings, 3mm oil ring
• Stroke length of 3.578" and connecting rod length of 6.243"
• Available in multiple compression ratios to suit different builds: 65cc dome for 12:1, 74cc dome for 10.73:1, and 85cc dome for 9.54:1
• Precision machining ensures tight tolerances and reliable sealing

Construction & Design:

Each piston in this set is forged from high-grade aluminum alloy, providing an excellent balance of strength, weight, and heat dissipation. The dome top design with a +4cc volume enhances combustion efficiency and allows for flexible compression ratio tuning. The pistons feature carefully engineered ring grooves to accommodate high-performance piston rings, ensuring optimal oil control and minimal blow-by.

The wrist pin bore is designed to accept either full-floating or press-fit pins, offering versatility depending on engine build preferences. The pistons are crafted to withstand the increased stresses of stroker crankshafts and higher cylinder pressures common in performance applications.

Installation & Fitment:

This piston set is designed to fit most Chrysler, Dodge, Jeep, and Ram 6.1L SRT8 engines equipped with Gen III Hemi blocks. Installation requires standard engine assembly procedures and may necessitate professional machining for precise cylinder bore sizing and ring fitting. The pistons are compatible with stroker crankshafts featuring a 3.578" stroke and connecting rods measuring 6.243".

Builders should verify compression ratio and clearances based on their specific build parameters. These pistons are ideal for custom stroker builds and high-performance rebuilds where durability and power gains are priorities.

What's Included:

• Set of forged pistons (quantity as required for engine configuration)
• Wrist pin compatibility for full-floating or press-fit installation
• Detailed specifications for piston dome volume and ring groove dimensions

Ideal For:

This piston set is perfect for engine builders, performance enthusiasts, and racers upgrading or rebuilding Chrysler, Dodge, Jeep, and Ram 6.1L SRT8 engines. It suits stroker builds aiming for increased displacement and power, as well as naturally aspirated or forced induction setups requiring robust, high-quality pistons capable of handling elevated cylinder pressures and RPM.
