• 6.5cc reverse dome design to optimize compression ratio and combustion
• Precision CNC-machined for exact bore and ring groove tolerances
• Includes premium piston rings engineered for high-performance sealing and reduced friction
• Designed for heavy to severe duty race engine applications
• Compatible with 4.080-inch bore size engines
• Enhanced skirt coatings to reduce friction and wear
• Balanced for high RPM stability and reduced vibration
• Custom-level performance features typically reserved for professional race teams

Construction & Design

Each Wiseco Professional Series piston is crafted from high-grade 2618 forged aluminum alloy, known for its excellent strength-to-weight ratio and resistance to thermal fatigue. The forging process ensures a dense, uniform grain structure that withstands the intense pressures of racing environments. The reverse dome design increases combustion efficiency by improving flame propagation and allowing precise control over compression ratios.

Advanced CNC machining guarantees tight tolerances on critical dimensions such as ring grooves and pin bores, ensuring optimal ring seal and piston-to-cylinder wall fitment. The pistons also feature specialized skirt coatings that minimize friction and wear, contributing to longer engine life and improved performance.

Installation & Fitment

These pistons are direct replacements for the factory pistons in 6.1L SRT8 engines found in the specified Chrysler, Dodge, and Jeep models. Installation requires standard engine rebuild procedures and should be performed by a qualified technician familiar with high-performance engine assembly. Proper ring end gap and piston clearance measurements are essential to ensure reliable operation under racing conditions. No major modifications to the engine block are typically necessary when upgrading to Wiseco Professional Series pistons.

What's Included
