Overview:
The DSS Racing Gen III Hemi FX Series Forged Piston Set is engineered specifically for the 6.1L SRT8 engines found in various Chrysler, Dodge, Jeep, and Ram models. Designed to meet the demanding needs of performance enthusiasts and professional builders, these pistons offer exceptional strength and durability under high-stress conditions. Whether you are upgrading your engine for increased power or rebuilding for reliability, this piston set delivers precision fitment and enhanced combustion efficiency.
Built to accommodate the 383 Small Block Mopar Hemi Gen III platform, these pistons feature a +4cc dome top design that optimizes compression ratios for improved power output. Their comp height of 1.21 inches and pin diameter of .927 inches ensure compatibility with full-floating or press-fit wrist pins, providing flexibility for various engine builds.
Key Features:
These forged pistons incorporate advanced design elements and manufacturing techniques to maximize performance and longevity:
Construction & Design:
Each piston in the DSS Racing FX Series is forged from high-grade aluminum alloy, providing an excellent balance of lightweight construction and structural integrity. The forging process enhances grain flow and material density, resulting in pistons that withstand extreme heat and pressure typical of high-performance and forced induction engines.
The dome top design with a +4cc volume increases the effective compression ratio, improving throttle response and power delivery without compromising reliability. The pistons are engineered with precise ring grooves to maintain optimal ring seal and reduce blow-by, contributing to improved engine efficiency and longevity.
Installation & Fitment:
These pistons are designed as direct replacements for the 6.1L SRT8 Gen III Hemi engines found in Chrysler, Dodge, Jeep, and Ram vehicles. Installation requires standard engine rebuild procedures and may involve balancing and blueprinting for optimal performance. The pistons accommodate either full-floating or press-fit wrist pins, allowing flexibility depending on your build preferences.
Due to their precise dimensions and compatibility with stock components, minimal modifications are necessary, making them an excellent choice for both performance upgrades and reliable rebuilds.

Ideal For:
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.
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!
