Overview:

The Ross Racing Forged Aluminum Pistons Set is engineered for high-performance Chrysler, Dodge, Jeep, and Ram engines, including the 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk variants. Designed to withstand the rigors of boosted and naturally aspirated applications, these pistons deliver exceptional strength and durability for enthusiasts seeking reliable power upgrades or engine rebuilds.

Ideal for racers, tuners, and performance builders, this set provides a direct fit solution that enhances engine efficiency and longevity. The pistons come complete with rings and are precision machined to exacting standards, ensuring optimal combustion and power delivery.

Key Features:

Ross Racing pistons incorporate advanced design and manufacturing techniques to meet the demands of high-output Hemi engines. Key features include:

• Forged aluminum construction for superior strength and lightweight performance
• Flat top piston design with two valve reliefs for improved valve clearance and combustion efficiency
• Precision bore size of 4.070 inches (103.378 mm) with a stroked engine stroke of 4.050 inches
• Compression height of 1.085 inches optimized for performance builds
• Press-fit or floating wrist pin options with a pin diameter of 0.927 inches
• File-fit piston rings included, measuring 1.20mm x 1.20mm x 3.00mm for reliable sealing
• Set of 8 pistons designed for complete engine rebuilds or upgrades
• Compatible with stroked engine configurations and 6.125-inch rod length

Construction & Design:

Each piston is crafted from high-grade forged aluminum, providing a perfect balance of strength and weight reduction. The flat top design with dual valve reliefs ensures maximum clearance for aggressive cam profiles and high-lift valve trains. This design also promotes efficient combustion chamber dynamics, contributing to improved power output and throttle response.

The pistons feature a compression height tailored to maintain proper deck clearance and piston-to-valve geometry in stroked engine builds. The wrist pins are designed for either press-fit or floating installation, allowing flexibility depending on engine requirements. Precision machining and file-fit rings guarantee a tight seal and reduced blow-by, enhancing engine reliability under demanding conditions.

Installation & Fitment:

This piston set is engineered as a direct replacement for Chrysler, Dodge, Jeep, and Ram 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk engines. Installation requires standard engine rebuild procedures and may involve custom tuning to optimize performance gains. No wrist pins or retainers are included, so these components must be sourced separately if needed.

Proper ring gap and piston clearance checks are recommended during installation to ensure optimal engine operation and longevity. These pistons are ideal for stroked engine configurations and high-performance builds requiring durable, lightweight components.

What's Included:

• Set of 8 forged aluminum pistons
• Piston rings (file-fit, non-gapless)

Ideal For:

This piston set is perfect for performance enthusiasts and professional engine builders upgrading or rebuilding Chrysler, Dodge, Jeep, and Ram Hemi engines. Whether you are enhancing a naturally aspirated 5.7L Hemi or building a high-output 6.2L Hellcat or Trackhawk, these pistons provide the strength and precision needed for reliable power gains and durability under extreme conditions.

Ross Racing Pistons manufactures forged aluminum pistons for serious motorsports and high-horsepower builds, offering both in-stock and fully custom piston programs for import and domestic engines.
