Overview:

JE Pistons is a renowned leader in the forged racing piston industry, bringing over 75 years of expertise to every product. This set of eight forged pistons is specifically engineered for the Mopar Gen 3 Hemi 6.2L engine with a 4.090-inch bore, commonly found in high-performance Hellcat applications. Designed and manufactured entirely in the USA, these pistons deliver exceptional durability and performance for racing and street engines alike. Whether you’re building a drag strip monster or a dirt track contender, JE Pistons provide proven reliability and strength that have earned victories across motorsports.

These pistons feature an inverted dome/dish design with a 1.280 compression height, optimized for the Gen III Hemi architecture. They are precision machined to exacting tolerances, ensuring a perfect fit and maximum efficiency in your engine build.

Key Features:

Engineered for high-performance Mopar Gen 3 Hemi 6.2L engines, these JE Pistons offer:

• Premium forged 2618 aluminum alloy for superior strength and fatigue resistance
• Precision CNC machining for tight tolerances and consistent performance
• Inverted dome/dish crown design tailored for optimal combustion and compression ratio
• 1.280-inch compression height for ideal piston-to-pin fitment
• Set of 8 pistons designed for V8 configurations
• Fully engineered for durability under extreme racing conditions
• 100% USA-made forging and machining processes
• Compatible with high-boost and high-RPM applications

Construction & Design:

Each piston is crafted from high-quality 2618 forged aluminum alloy, known for its excellent strength-to-weight ratio and resistance to thermal fatigue. JE Pistons employs advanced forging techniques combined with precision CNC machining to produce pistons that maintain structural integrity under the intense pressures of forced induction and high RPM operation. The inverted dome/dish crown design is optimized to enhance combustion efficiency and control detonation, making these pistons ideal for boosted Hellcat engines and other high-performance Mopar builds.

Attention to detail in the piston skirt profile and ring land design reduces friction and wear, contributing to longer engine life and improved power output. The pistons are engineered to exact specifications for the 4.090-inch bore size, ensuring a precise fit and reliable sealing with compatible rings and cylinders.

Installation & Fitment:

This piston set is designed specifically for the Mopar Gen 3 Hemi 6.2L engine platform, including Hellcat variants. Installation requires standard engine rebuild procedures and is best performed by experienced engine builders familiar with high-performance Mopar engines. No major modifications are typically needed when replacing stock pistons with this JE set, but proper ring selection and clearances should be verified to ensure optimal performance and longevity.

What's Included:

• Set of 8 forged JE Pistons for Gen 3 Hemi 6.2L 4.090-inch bore

Ideal For:

This piston set is ideal for enthusiasts and professional builders upgrading or rebuilding Mopar Gen III Hemi 6.2L engines, especially those seeking enhanced durability and performance for drag racing, street performance, or other motorsports applications.
