Overview:

The DSS Racing 6.1 Stroker Small Block Mopar Hemi Gen III FX Series Forged Piston Set is engineered specifically for high-performance applications in Chrysler, Dodge, Jeep, and Ram vehicles equipped with the 6.1L SRT8 engine. Designed to handle increased stroke and compression demands, these pistons provide a reliable upgrade for enthusiasts seeking enhanced durability and power potential.

Built to accommodate a 4.050" stroke and compatible with rod lengths of 6.125", this piston set is ideal for stroker engine builds that require precision and strength. The pistons feature a -7cc dish top design and a compact 1.09" compression height, making them suitable for a variety of performance configurations while maintaining optimal combustion chamber volume.

Key Features:

These forged pistons incorporate advanced design elements to maximize engine efficiency and longevity. Key features include:

• Forged construction for superior strength and resistance to high stress
• Comp height of 1.09" optimized for stroker builds
• 7cc dish top to control compression and prevent detonation
• .927" wrist pin diameter compatible with full-floating or press-fit configurations
• Ring groove dimensions of 1.2mm/1.2mm/3mm for reliable sealing and reduced friction
• Designed for a 4.050" stroke and 6.125" connecting rods
• Available in multiple dish volumes (65cc, 74cc, 85cc) to achieve compression ratios from approximately 9.56:1 to 11.69:1
• Precision machining ensures consistent fit and performance

Construction & Design:

DSS Racing pistons are crafted from high-grade forged aluminum alloy, delivering an optimal balance of lightweight strength and thermal conductivity. The forging process enhances grain structure, resulting in pistons that withstand the rigors of high RPM and boost pressures common in performance engines.

The piston design incorporates a carefully engineered dish volume to manage compression ratios effectively, reducing the risk of knock while maximizing power output. The wrist pin bore is engineered for compatibility with both full-floating and press-fit pins, allowing flexibility in assembly preferences.

Installation & Fitment:

This piston set is designed to fit most Chrysler, Dodge, Jeep, and Ram vehicles equipped with the 6.1L SRT8 engine, including Gen III small block Mopar Hemis. Installation requires standard engine rebuild procedures and may necessitate matching the pistons to compatible rods and crankshafts based on the stroker specifications.

Due to the precise dimensions and compression heights, these pistons are ideal for custom stroker builds and performance upgrades. Professional installation is recommended to ensure proper clearances and optimal engine performance.

What's Included:

• Set of forged pistons (quantity as required per engine)
• Wrist pins compatible with full-floating or press-fit installation
• Ring grooves pre-machined for 1.2mm top and second rings, 3mm oil ring

Ideal For:

This piston set is perfect for engine builders and performance enthusiasts upgrading or rebuilding 6.1L SRT8 engines who demand enhanced durability and the ability to support increased stroke and compression. Whether building a street performance stroker or a track-focused powerplant, these pistons provide a solid foundation for reliable power gains.

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.
