Overview:
The DSS Racing FX Series Forged Piston Set is engineered specifically for the Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines, including the 347 Small Block Mopar Hemi Gen III. Designed to deliver superior strength and durability, these pistons are ideal for enthusiasts and professional builders looking to enhance engine performance and reliability. Whether you are upgrading for street performance, racing, or heavy-duty applications, this piston set offers a precise fit and excellent combustion efficiency.
With a bore size of 3.927 inches and a compression height of 1.21 inches, these pistons are crafted to optimize combustion chamber dynamics while maintaining compatibility with stock and aftermarket components. The -12cc dish top design helps control compression ratios, making them versatile for various build specifications.
Key Features:
These forged pistons incorporate advanced design elements and high-quality materials to meet the demands of high-performance 5.7L Hemi engines:
- Forged construction for enhanced strength and durability under high stress
- 3.927" bore diameter to fit most Chrysler / Dodge / Jeep / Ram 5.7L Hemi engines
- 12cc dish top design to optimize compression and combustion efficiency
- Full-floating or press-fit wrist pin options for reliable piston-to-rod connection
- Ring groove dimensions: 1.2mm top and second rings, 3mm oil ring for effective sealing
- Compatible with a 3.578" stroke and 6.243" connecting rods
- Available in multiple dish volumes (65cc, 74cc, 85cc) to accommodate different compression ratios
- Precision-machined for tight tolerances and consistent performance
Construction & Design:
The DSS Racing FX Series pistons are forged from premium-grade aluminum alloy, providing an optimal balance of lightweight construction and exceptional strength. The forging process enhances grain structure, increasing resistance to fatigue and thermal stress commonly encountered in high-performance engines. The pistons feature a carefully engineered dish top design with a -12cc volume to help manage compression ratios and prevent detonation.
Each piston is CNC-machined to exact specifications, ensuring perfect ring groove dimensions and pin bore alignment. The option for full-floating or press-fit wrist pins allows builders to tailor the piston assembly to their specific application and durability requirements. This attention to detail guarantees a reliable and long-lasting component that performs consistently under demanding conditions.
Installation & Fitment:
These pistons are designed to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines, including the 347 Small Block Mopar Hemi Gen III. Installation requires standard engine rebuilding procedures and may involve balancing and blueprinting for optimal results. The pistons are compatible with a 3.927" bore and work with a 3.578" stroke and 6.243" connecting rods, making them suitable for many popular Hemi builds.
Builders should verify clearances and ring end gaps during installation to ensure proper fitment and performance. No major modifications are typically necessary, but professional installation is recommended to maximize the benefits of these forged pistons.
What's Included:
- Set of forged pistons (quantity as per engine requirements)
- Wrist pins (full-floating or press-fit, depending on selection)
- Snap rings or retainers for wrist pins
Ideal For:
This piston set is ideal for automotive enthusiasts, engine builders, and racers seeking to upgrade or rebuild their 5.7L Hemi engines with high-quality forged components. Whether building a street performance engine, a drag racing powerplant, or a heavy-duty off-road machine, these pistons provide the strength and reliability needed to handle increased power and stress.
They are especially suited for those who require precise compression control and durability in demanding applications, ensuring long-term engine health and consistent performance.

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!
