Overview:
The DSS Racing 5.7 Stroker Small Block Mopar Hemi Gen III FX Series Forged Piston Set is engineered for enthusiasts and builders seeking reliable, high-performance components for their 5.7L Hemi engines. Designed to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi models, these pistons are ideal for stroker builds and high-output applications. With a forged construction and precision engineering, this piston set offers enhanced strength, durability, and improved combustion efficiency to support increased power and engine longevity.
Whether you are upgrading your engine for street performance, racing, or heavy-duty use, these pistons provide the foundation for a robust and efficient powerplant capable of handling increased stroke and compression ratios.
Key Features:
Built to exacting standards, the DSS Racing FX Series Forged Pistons deliver a range of technical advantages:
- Compatible with 5.7L Small Block Mopar Hemi Gen III engines featuring a 3.795" stroke and 6.125" rod length
- Forged construction for superior strength and resistance to high stress and heat
- Comp height of 1.21" with a +9cc dome top design to optimize combustion chamber volume
- .927" wrist pin diameter available in full-floating or press-fit options for secure piston-to-rod connection
- Ring groove dimensions of 1.2/1.2/3mm to accommodate high-performance piston rings
- Multiple compression ratio options based on combustion chamber volume: 65cc (12.86:1), 74cc (11.4:1), and 85cc (10.04:1)
- Precision machining ensures tight tolerances and consistent performance across all pistons
- Designed specifically for stroker applications to maximize displacement and power potential
Construction & Design:
The DSS Racing FX Series pistons are crafted from high-grade forged aluminum alloy, providing an optimal balance of lightweight design and exceptional strength. The forging process enhances the metal’s grain structure, resulting in pistons that withstand the rigors of high RPM and elevated cylinder pressures common in performance engines.
The +9cc dome top design improves combustion efficiency by optimizing the compression ratio and flame propagation within the chamber. The pistons feature precise ring grooves and wrist pin bores engineered for durability and minimal friction, contributing to overall engine reliability and efficiency.
Installation & Fitment:
This piston set is designed to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines, particularly those utilizing the Gen III Small Block Mopar Hemi platform. Installation requires standard engine assembly procedures and may involve balancing and blueprinting for stroker builds. The availability of both full-floating and press-fit wrist pin options allows for customization based on builder preference and application requirements.
Professional installation is recommended to ensure proper clearances and optimal engine performance.
What's Included:
- Set of forged pistons (quantity as required for engine configuration)
- Wrist pins (full-floating or press-fit, depending on selected option)
- Installation instructions and technical specifications
Ideal For:
- Engine builders upgrading or rebuilding 5.7L Hemi engines for increased displacement
- Performance enthusiasts seeking durable pistons for street or track use
- Stroker engine applications requiring precise piston dimensions and compression ratios
- Motorsport and racing teams demanding reliable forged components for high RPM operation

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
