• 4.075" bore size tailored for 373 Small Block Mopar Hemi Gen III applications
• Compact dish top with -12cc volume to optimize combustion chamber shape
• Pin diameter of .984" with options for full-floating or press-fit configurations
• Ring groove dimensions of 1.2mm / 1.2mm / 3mm for reliable ring sealing
• Stroke length of 3.578" and connecting rod length of 6.243" for precise engine geometry
• Available in multiple compression ratios approximately ranging from 8.24 to 9.93 depending on combustion chamber volume
• Forged construction for enhanced strength and resistance to high-stress conditions

Construction & Design:

DSS Racing FX Series pistons are forged from high-quality aluminum alloy, providing an excellent balance of lightweight design and structural integrity. The forging process enhances grain structure and strength, allowing these pistons to withstand the high pressures and temperatures typical of high-performance Hemi engines.

The pistons feature a carefully engineered dish top design with a -12cc volume that helps control compression and combustion characteristics. Precision machining ensures tight tolerances for optimal fitment and performance, while the choice between full-floating or press-fit wrist pins allows customization based on engine build preferences.

Installation & Fitment:

These pistons are designed as direct replacements for the 6.1L SRT8 Gen III Hemi engines found in Chrysler, Dodge, Jeep, and Ram vehicles. Installation requires standard engine assembly procedures, with attention to proper ring end gap and wrist pin installation based on the selected pin configuration.

Due to their exact bore and stroke specifications, these pistons fit seamlessly into compatible engine blocks without the need for extensive modifications, making them suitable for both rebuilds and performance upgrades.

What's Included:

• Set of four DSS Racing FX Series forged pistons (4.075" bore)
• Wrist pins (.984" diameter) with options for full-floating or press-fit installation
• Precision-machined piston rings with 1.2/1.2/3mm groove dimensions
• Technical specifications and installation guidelines

Ideal For:

These pistons are ideal for automotive enthusiasts, engine builders, and professional racers who demand reliable, high-strength components for their 6.1L SRT8 Gen III Hemi engines. Whether upgrading for increased power output, durability, or engine longevity, the DSS Racing FX Series pistons provide a solid foundation for performance builds and rebuilds alike.
