Overview:

The DSS Racing FX Series Forged Flat Top Pistons Set is engineered specifically for Chrysler, Dodge, Jeep, and Ram vehicles equipped with the 5.7L Hemi engine. Designed to meet the demands of high-performance and rebuild applications, these pistons offer a reliable upgrade over stock components. Featuring a flat top design with a compact combustion chamber volume, they help optimize compression ratios for improved power and efficiency.

Ideal for enthusiasts and professional builders alike, this piston set supports both full-floating and press-fit wrist pin configurations, providing versatility to suit various engine builds. Whether you are restoring your Hemi or upgrading for enhanced performance, DSS Racing pistons deliver durability and precision engineering.

Key Features:

These forged pistons incorporate advanced design elements to ensure strength, reliability, and performance in demanding conditions:

• Compatible with 350 Small Block Mopar Hemi Gen III engines
• Flat top piston crown with -1.5cc volume for optimized combustion
• Compression height of 1.21 inches for precise deck clearance
• .927 inch wrist pin diameter available in full-floating or press-fit options
• Ring groove dimensions: 1.2mm top and second grooves, 3mm oil ring groove
• Designed for a 3.578 inch stroke and 6.243 inch connecting rods
• Available in multiple combustion chamber volumes (65cc, 74cc, 85cc) to achieve compression ratios from approximately 8.54:1 to 10.55:1
• Forged construction for superior strength and durability under high stress

Construction & Design:

DSS Racing FX Series pistons are forged from high-quality aluminum alloy, providing an excellent balance of lightweight characteristics and strength. The forging process enhances the metal grain structure, resulting in pistons that resist cracking and deformation under extreme heat and pressure. The flat top design promotes efficient combustion and helps maintain consistent compression ratios across various engine configurations.

The pistons feature precision-machined ring grooves and pin bores to ensure proper sealing and smooth articulation with the connecting rods. The option for full-floating or press-fit wrist pins allows builders to tailor the assembly to their specific performance goals and engine setup.

Installation & Fitment:

These pistons are designed as direct replacements for most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines, making installation straightforward for experienced engine builders. Minimal modifications are typically required when upgrading from stock pistons, but proper measurement and clearancing should be performed to ensure optimal fitment and performance. DSS Racing pistons are compatible with standard 3.578 inch stroke crankshafts and 6.243 inch connecting rods common to these engines.

What's Included:

• Set of forged flat top pistons (quantity as required for engine)
• Wrist pins (.927 inch diameter), available in full-floating or press-fit configurations
• Detailed specifications for compression height, ring groove dimensions, and combustion chamber volumes

Ideal For:

This piston set is perfect for performance enthusiasts, engine builders, and professional shops looking to upgrade or rebuild Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines. Whether your goal is increased horsepower, improved reliability, or a custom compression ratio setup, DSS Racing FX Series pistons provide a durable and precise foundation for your build.
