Overview:

The DSS Racing FX Series Forged Pistons are precision-engineered performance components designed specifically for the 6.2L Hellcat Gen III Hemi engines found in many Chrysler, Dodge, Jeep, and Ram models. Crafted to meet the demanding requirements of high-performance and racing applications, these pistons offer exceptional strength, durability, and reliability under extreme conditions.

Ideal for enthusiasts and professional builders looking to upgrade their engine’s internals, these pistons provide improved combustion efficiency and enhanced resistance to heat and stress. Whether you are building a street performance engine or a track-ready powerhouse, the DSS Racing FX Series pistons deliver the quality and performance needed to maximize your Hellcat’s potential.

Key Features:

Designed with advanced engineering and manufacturing techniques, the DSS Racing FX Series Forged Pistons include the following key features:

• Compatible with 4.100" bore size for 6.2L Hellcat Gen III Hemi engines
• Forged construction for superior strength and durability compared to cast pistons
• Comp height of 1.275" optimized for performance builds
• 10cc dish top design to control compression ratio and improve combustion
• .927" wrist pin diameter with options for full-floating or press-fit pins
• Ring groove dimensions of 1.2mm / 1.2mm / 3mm for reliable ring sealing and reduced friction
• Compatible with 3.578" stroke and 6.2" connecting rods
• Available with various dish volumes to achieve approximate compression ratios ranging from 8.48 to 10.26
• Precision CNC-machined for exact fitment and balanced performance

Construction & Design:

The DSS Racing FX Series pistons are forged from high-grade aluminum alloy, providing an optimal balance of lightweight design and exceptional strength. Forging enhances the grain structure of the metal, resulting in pistons that resist cracking, scuffing, and thermal fatigue even under high boost and elevated RPM conditions.

Each piston features a carefully engineered dish top to manage combustion chamber volume and compression ratio, allowing tuners to tailor engine performance to specific applications. The wrist pins are designed for either full-floating or press-fit installation, offering flexibility depending on engine build preferences. Ring grooves are precision-cut to accommodate performance rings that maintain excellent sealing and durability.

Installation & Fitment:

These pistons are direct replacements for 6.2L Hellcat Gen III Hemi engines and fit most Chrysler, Dodge, Jeep, and Ram models equipped with this powerplant. Installation requires standard engine assembly procedures and attention to proper clearances and torque specifications. The pistons are compatible with factory or aftermarket connecting rods measuring 6.2" in length and a stroke of 3.578".

Due to their forged construction and design specifications, these pistons are ideal for high-performance builds, including forced induction and naturally aspirated applications. Professional installation is recommended to ensure optimal engine performance and longevity.

What's Included:

• Set of forged pistons sized for 4.100" bore
• Wrist pins (.927") with options for full-floating or press-fit
