• Comp height of 1.275" tailored for Gen III Mopar Hemi 383 Small Block applications
• Stroke compatibility of 3.578" and connecting rod length of 6.2" for precise engine geometry
• Available in multiple dish volumes (65cc, 74cc, 85cc) to support compression ratios from 8.56 to 10.37
• Engineered to withstand high cylinder pressures typical of Hellcat supercharged setups
• Direct fitment for most Chrysler, Dodge, Jeep, and Ram 6.2L Hellcat and Trackhawk engines

Construction & Design:

The FX Series pistons are crafted from high-grade forged aluminum alloy, providing an excellent strength-to-weight ratio that reduces reciprocating mass and improves throttle response. The forging process enhances grain structure and fatigue resistance, ensuring long-lasting durability under extreme operating conditions.

Each piston features a carefully calculated dish volume to optimize combustion chamber shape and compression ratio, enhancing power output and efficiency. The ring grooves are precision-machined to accommodate high-performance piston rings, ensuring superior sealing and oil control. The wrist pin design supports both full-floating and press-fit configurations, allowing flexibility for various engine builds.

Installation & Fitment:

These DSS Racing FX Series Forged Pistons are designed as direct replacements for the factory pistons in most 6.2L Gen III Mopar Hemi Hellcat and Trackhawk engines. Installation requires standard engine assembly procedures, and no major modifications are necessary when paired with compatible rods and crankshafts. Proper ring end gap and clearance checks are recommended during installation to ensure optimal performance and longevity.

What's Included:

• Set of 8 DSS Racing FX Series Forged Pistons
• Compatible wrist pins (full-floating or press-fit options)
• Detailed specifications and installation guidelines

Ideal For:

These forged pistons are ideal for performance enthusiasts, engine builders, and racers who demand reliable, high-strength components for their 6.2L Hellcat or Trackhawk engines. Whether upgrading for forced induction, high-boost applications, or naturally aspirated builds seeking improved durability and compression tuning, the DSS Racing FX Series pistons provide a solid foundation for serious power gains and engine longevity.
