Key Features:

Ross Racing pistons combine advanced engineering with premium materials to offer superior performance and longevity. Key features include:

• Forged aluminum construction for maximum strength and reduced weight
• Dish-style piston design with two valve reliefs for improved valve clearance and combustion efficiency
• Compression height of 1.085 inches and piston head volume of +18.00cc for optimized combustion chamber dynamics
• Compatible with press-fit or floating wrist pins, providing flexibility in engine assembly
• Includes piston rings with thicknesses of 1.20mm x 1.20mm x 3.00mm, file fit for precise sealing
• Pin diameter of 0.927 inches with included wrist pin retainers for secure installation
• Designed for stroked engines with a bore of 4.070 inches (103.378mm) and stroke of 4.050 inches
• Rod length compatibility of 6.125 inches for proper piston-to-rod geometry
• Sold as a complete set of eight pistons, ideal for V8 engine configurations

Construction & Design:

Crafted from high-grade forged aluminum, these pistons offer an excellent balance of strength and lightweight characteristics essential for high-performance applications. The forging process enhances the metal's grain structure, resulting in pistons that resist cracking and deformation under extreme stress. The dish-style piston crown with dual valve reliefs ensures adequate clearance for aggressive cam profiles and high-lift valve trains, reducing the risk of valve-to-piston contact.

The precise compression height and piston head volume are engineered to maintain optimal compression ratios, contributing to efficient combustion and power delivery. The inclusion of wrist pin retainers and compatibility with both press-fit and floating wrist pins allows for versatile engine assembly options tailored to specific build requirements.

Installation & Fitment:

This piston set is designed to fit Chrysler, Dodge, Jeep, and Ram engines equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk powerplants. Installation requires standard engine rebuilding procedures, including precise bore sizing and honing to 4.070 inches. The pistons are file-fit for piston rings, ensuring a custom seal for each application. Due to their design for forced induction setups, these pistons are ideal for builds involving superchargers or turbochargers.

Professional installation is recommended to ensure proper clearances, ring gap settings, and overall engine balance. This set does not include wrist pins, so be sure to source compatible pins if not reusing existing components.

What's Included:

• Set of 8 forged aluminum pistons
• Piston rings (1.20mm x 1.20mm x 3.00mm thickness)
• Wrist pin retainers

Ideal For:

This piston set is ideal for performance enthusiasts, engine builders, and racers upgrading or rebuilding Chrysler, Dodge, Jeep, and Ram V8 engines for forced induction applications. Whether you are boosting a 5.7L Hemi or pushing the limits of a Hellcat or Trackhawk, these pistons provide the durability and precision needed to handle increased power levels reliably.

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. Family-run with decades of racing focus and U.S. manufacturing, Ross is a trusted choice when strength, precision machining, and reliability under boost or high RPM are non-negotiable.
