Whether you are rebuilding your engine or upgrading for increased power output, the DSS Racing FX Series pistons offer a perfect balance of strength, weight, and compatibility with factory components.

Key Features:

These forged pistons incorporate advanced design elements to optimize performance and durability. Key features include:

• Compatible with 368 Small Block Mopar Hemi Gen III engines and FX series configurations
• Forged construction for superior strength and resistance to high-stress conditions
• Compact 1.21" compression height for precise fitment in stroker applications
• 12cc dish top design to optimize combustion chamber volume and compression ratio
• .927" wrist pin diameter with options for full-floating or press-fit installation
• Ring groove dimensions of 1.2mm / 1.2mm / 3mm for reliable ring sealing and durability
• Designed for a 3.795" stroke and 6.125" connecting rods, supporting stroker builds
• Available in multiple dish volumes (65cc, 74cc, 85cc) to tailor compression ratios from approximately 9.88:1 to 8.19:1

Construction & Design:

Each piston in this set is crafted from high-grade forged aluminum alloy, ensuring exceptional strength while maintaining a lightweight profile. The forging process enhances the metal’s grain structure, providing superior fatigue resistance and durability under extreme combustion pressures. The dish top design reduces the compression ratio to accommodate higher boost or nitrous applications without risking detonation.

The pistons feature precision-machined ring grooves and a wrist pin bore designed for either full-floating or press-fit pins, allowing flexibility depending on your engine build preferences. This attention to detail ensures optimal sealing, reduced friction, and long-lasting performance in demanding environments.

Installation & Fitment:

This piston set is engineered to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines, particularly those utilizing the Gen III small block Mopar Hemi platform. Installation requires standard engine rebuilding procedures and may involve balancing with your chosen connecting rods and crankshaft to achieve optimal performance and reliability.

Due to the specific compression heights and dish volumes, these pistons are ideal for stroker engine builds with a 3.795" stroke and 6.125" rods. Proper clearancing and ring end gap adjustments are recommended to ensure smooth operation and longevity.

What's Included:

• Set of forged pistons (quantity as per engine requirements)
• Wrist pins compatible with full-floating or press-fit installation
• Precision-machined piston rings (1.2mm top and second rings, 3mm oil ring)
• Installation instructions and technical specifications

Ideal For:

This piston set is perfect for engine builders and performance enthusiasts upgrading or rebuilding their 5.7L Hemi engines for increased power, reliability, and efficiency. It suits stroker builds, forced induction setups, and naturally aspirated engines requiring stronger pistons to handle elevated cylinder pressures. Whether for street performance, drag racing, or off-road applications, these pistons provide a durable foundation for high-performance Mopar Hemi engines.
