Overview:

The DSS Racing 5.7L Stroker Gen III Hemi Forged Piston Set is engineered for enthusiasts and professionals seeking to upgrade their Chrysler, Dodge, Jeep, or Ram 5.7L Hemi engines. Designed specifically for the Gen III Hemi platform, these pistons are ideal for stroker builds, offering enhanced durability and performance. Whether you are building a high-performance street engine or a race-ready powerplant, this piston set provides the strength and precision needed to handle increased power and higher RPMs.

These forged pistons feature a -12cc dish top design and are compatible with a 3.795" stroke and 6.125" connecting rods, making them a perfect match for 373 cubic inch small block Mopar Hemi stroker configurations. Their comp height of 1.21" and ring groove dimensions ensure optimal sealing and combustion efficiency, contributing to improved engine reliability and power output.

Key Features:

Built to meet the demands of high-performance 5.7L Hemi engines, the DSS Racing forged piston set offers the following key features:

• Compatible with Chrysler, Dodge, Jeep, and Ram 5.7L Hemi Gen III engines
• Forged construction for superior strength and durability under high stress
• 12cc dish top design to optimize compression and combustion
• Pin diameter of .927" with options for full-floating or press-fit pins
• Ring groove dimensions of 1.2mm/1.2mm/3mm for effective ring sealing
• Designed for a 3.795" stroke and 6.125" connecting rods, ideal for stroker builds
• Available in multiple compression ratios: 65cc (9.98:1), 74cc (9.12:1), and 85cc (8.27:1)
• Precision machined for consistent fitment and performance

Construction & Design:

These pistons are forged from high-grade aluminum alloy, providing an excellent balance of lightweight design and mechanical strength. Forging enhances the grain structure of the metal, resulting in pistons that resist cracking, scuffing, and thermal fatigue even under extreme operating conditions. The dish top design reduces compression volume to accommodate higher boost or nitrous applications while maintaining efficient combustion chamber dynamics.

The pistons feature carefully engineered ring grooves to maintain ring stability and reduce blow-by, contributing to improved oil control and engine longevity. The option for full-floating or press-fit wrist pins allows builders to tailor the setup to their specific performance and durability requirements.

Installation & Fitment:

The DSS Racing forged piston set is designed to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi Gen III engines with minimal modifications. These pistons are optimized for use with a 3.795" stroke crankshaft and 6.125" connecting rods, commonly found in 373 stroker builds. Installation should be performed by experienced engine builders or professionals familiar with high-performance Hemi engine assembly to ensure proper clearances and torque specifications are met.

Due to the precision manufacturing and fitment specifications, these pistons drop into the block with excellent consistency, reducing the need for extensive machining or custom fitting. Always verify compatibility with your specific engine components before installation.

What's Included:

• Set of forged pistons (quantity as required for engine)
• Wrist pins (full-floating or press-fit options depending on SKU)
• Ring sets with 1.2mm top and second rings, 3mm oil rings
• Installation instructions and technical specifications

Ideal For:

This piston set is ideal for performance enthusiasts, engine builders, and racers upgrading or rebuilding Chrysler, Dodge, Jeep, or Ram 5.7L Hemi engines. It suits stroker engine builds aiming for increased displacement and power output, including street performance, drag racing, and other motorsport applications where durability and reliability are critical.
