1-6806-4075 / 2-6806-4075 / 3-6806-4075 / K1-6806-4075 / K2-6806-4075 / K3-6806-4075

Overview:

The DSS Racing 6.1 Stroker FX Series Forged Piston Set is engineered specifically for the Chrysler, Dodge, Jeep, and Ram 6.1L SRT8 engines, including the 423 Small Block Mopar Hemi Gen III platform. Designed to accommodate a 4.075" bore and a 4.050" stroke, these pistons are ideal for enthusiasts and builders seeking enhanced durability and performance in their stroker engine builds.

These forged pistons offer a precise comp height of 1.09" and feature a -23cc dish top design, allowing for optimized combustion chamber volume and compression ratios tailored to your build. Whether you are upgrading for street performance, track use, or high-output applications, this piston set provides the strength and reliability required for demanding conditions.

Key Features:

Built with performance and reliability in mind, the DSS Racing FX Series pistons include:

• Forged construction for superior strength and durability under high stress
• 4.075" bore size compatible with most 6.1L SRT8 stroker builds
• 23cc dish top design to optimize combustion and compression ratios
• Comp height of 1.09" for precise piston-to-deck clearance
• Ring groove dimensions of 1.2mm / 1.2mm / 3mm for effective sealing
• Pin diameter of .927" with options for full-floating or press-fit installation
• Designed for use with a 4.050" stroke crankshaft and 6.125" connecting rods
• Approximate compression ratios ranging from 8.44:1 to 9.98:1 depending on combustion chamber volume
• Compatible with 65cc, 74cc, and 85cc combustion chambers for flexible build options

Construction & Design:

These pistons are crafted from high-grade forged aluminum alloy, providing an excellent balance of lightweight strength and thermal conductivity. The forging process enhances grain structure and mechanical properties, ensuring the pistons withstand the rigors of high-performance and high-RPM operation.

The dish top design reduces compression to prevent detonation in boosted or high-compression applications, while the precise machining of ring grooves and pin bores ensures optimal ring seal and wrist pin fitment. The option for full-floating or press-fit pins allows builders to tailor the piston assembly to their specific engine requirements.

Installation & Fitment:

The DSS Racing FX Series Forged Pistons are designed as direct replacements for most Chrysler, Dodge, Jeep, and Ram 6.1L SRT8 engines with a 4.075" bore. Installation requires standard engine assembly procedures, including proper ring end gap setting and wrist pin installation based on the chosen pin retention method.

These pistons are ideal for stroker builds using a 4.050" stroke crankshaft and 6.125" connecting rods. Builders should verify clearances and compression ratios based on their specific cylinder heads and deck height to ensure optimal performance and reliability.

What's Included:

• Set of 8 DSS Racing FX Series Forged Pistons
• Wrist pins (full-floating or press-fit depending on SKU)
• Snap rings or pin retainers as applicable

Ideal For:

This piston set is perfect for engine builders and performance enthusiasts upgrading or rebuilding Chrysler, Dodge, Jeep, or Ram 6.1L SRT8 engines. It suits stroker engine projects aiming for increased displacement, improved strength, and reliable power delivery in street, strip, or track environments.
