Overview:
The DSS Racing 6.1 Stroker Gen III Hemi FX Series Forged Piston Set is engineered specifically for the Chrysler, Dodge, Jeep, and Ram 6.1L SRT8 engines. Designed to handle the increased demands of stroker builds and high-performance applications, these pistons offer enhanced strength and durability over stock components. Ideal for enthusiasts and professional builders seeking reliable, high-quality pistons that maintain factory compatibility while delivering improved performance and longevity.
These pistons are precision-crafted to fit the 418 Small Block Mopar Hemi Gen III platform, making them a perfect upgrade for those looking to maximize their engine’s potential without compromising reliability.
Key Features:
Built with advanced engineering and materials, the DSS Racing FX Series pistons provide a range of benefits tailored for high-performance 6.1L SRT8 engines:
- Forged construction for superior strength and resistance to detonation
- Compensated dish top design with -23cc volume for optimized compression ratios
- Pin diameter of .927" compatible with full-floating or press-fit configurations
- Ring groove dimensions of 1.2mm / 1.2mm / 3mm for reliable ring sealing and durability
- Stroke compatibility of 4.050" and connecting rod length of 6.125" for stroker engine builds
- Available in multiple dish volumes (65cc, 74cc, 85cc) to achieve compression ratios ranging from 8.35 to 9.87
- Precision machining ensures consistent fitment and performance
- Designed to withstand the rigors of high RPM and forced induction setups
Construction & Design:
The DSS Racing FX Series pistons are forged from high-grade aluminum alloy, providing an excellent balance of lightweight properties and exceptional strength. The forging process enhances the grain structure of the metal, resulting in pistons that resist cracking and deformation under extreme thermal and mechanical stress.
Each piston features a carefully engineered dish top with a -23cc volume to optimize combustion chamber shape and compression ratio, improving power output and efficiency. The piston pin bore is designed to accommodate either full-floating or press-fit pins, offering flexibility depending on engine build preferences. Ring grooves are precision-cut to maintain ring seal integrity and reduce wear over time.
Installation & Fitment:
This piston set is designed as a direct fit for most Chrysler, Dodge, Jeep, and Ram 6.1L SRT8 engines using the Gen III Hemi platform. Installation requires standard engine assembly procedures, and no major modifications are typically necessary when replacing stock pistons with this set. Proper ring end gap and clearance checks should be performed to ensure optimal performance and longevity.
Compatible with stroker builds featuring a 4.050" stroke and 6.125" connecting rods, these pistons allow for increased displacement and power potential while maintaining factory-style reliability.
What's Included:
- Set of forged pistons (quantity as required for engine configuration)
- Precision-machined piston rings with specified groove dimensions
- Compatible wrist pins (full-floating or press-fit options)
- Installation instructions and technical specifications
Ideal For:
This piston set is ideal for performance enthusiasts, engine builders, and racers upgrading or rebuilding Chrysler, Dodge, Jeep, or Ram 6.1L SRT8 engines. It is especially suited for stroker engine configurations and applications demanding enhanced durability and compression control, including naturally aspirated and forced induction setups.
DSS Racing — Founded in 1983 originally as Danny’s Speed Shop, DSS Racing has grown from a small Midwest performance engine shop into a respected name in forged engine components for the high-performance and racing markets. Based in St. Charles, Illinois, DSS is best known for its forged pistons and machined engine parts made in the USA that have been used in championship engines and thousands of builds, blending old-school racing roots with precision manufacturing for enthusiasts and racers alike.

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!
