• Precision CNC machining ensures exact bore and dimensional tolerances (3.927 inch bore)
• Designed to withstand heavy to severe duty racing environments and high RPM operation
• Includes premium piston rings engineered for optimal sealing and reduced friction
• Professional Series pistons are built to remove limits and support aggressive engine builds

Construction & Design:

Each piston is forged using Wiseco’s state-of-the-art forging process, which produces a dense, uniform grain structure for maximum strength and fatigue resistance. The +19cc dome shape is carefully designed to optimize combustion chamber shape and compression ratio, improving power output and efficiency.

The pistons feature a robust pin boss and wrist pin bore to accommodate the 0.945 inch pin diameter, ensuring secure connection to the connecting rods under high loads. The 1.220 inch compression height is engineered for precise piston-to-deck clearance in the 5.7L HEMI block, promoting reliable operation and consistent performance.
