Key Features:

Built to exacting standards, the DSS Racing FX Series Forged Pistons deliver a range of technical advantages:

• Compatible with 5.7L Small Block Mopar Hemi Gen III engines featuring a 3.795" stroke and 6.125" rod length
• Forged construction for superior strength and resistance to high stress and heat
• Comp height of 1.21" with a +9cc dome top design to optimize combustion chamber volume
• .927" wrist pin diameter available in full-floating or press-fit options for secure piston-to-rod connection
• Ring groove dimensions of 1.2/1.2/3mm to accommodate high-performance piston rings
• Multiple compression ratio options based on combustion chamber volume: 65cc (12.86:1), 74cc (11.4:1), and 85cc (10.04:1)
• Precision machining ensures tight tolerances and consistent performance across all pistons
• Designed specifically for stroker applications to maximize displacement and power potential

Construction & Design:

The DSS Racing FX Series pistons are crafted from high-grade forged aluminum alloy, providing an optimal balance of lightweight design and exceptional strength. The forging process enhances the metal’s grain structure, resulting in pistons that withstand the rigors of high RPM and elevated cylinder pressures common in performance engines.

The +9cc dome top design improves combustion efficiency by optimizing the compression ratio and flame propagation within the chamber. The pistons feature precise ring grooves and wrist pin bores engineered for durability and minimal friction, contributing to overall engine reliability and efficiency.

Installation & Fitment:

This piston set is designed 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 assembly procedures and may involve balancing and blueprinting for stroker builds. The availability of both full-floating and press-fit wrist pin options allows for customization based on builder preference and application requirements.

Professional installation is recommended to ensure proper clearances and optimal engine performance.
