Whether you are building a track-focused race engine or a high-output street machine, Wiseco’s Professional Series pistons deliver the quality and engineering to support your goals.

Each piston comes with premium rings and features a 1.080 inch compression height and a 0.866 inch pin diameter, ensuring a perfect fit and reliable operation in your 6.1L HEMI build.

Key Features:

Wiseco’s Professional Series pistons incorporate advanced design and manufacturing techniques to meet the demands of high-performance racing engines:

• Fully forged construction for maximum strength and durability under extreme conditions
• 28cc dish design to optimize combustion chamber volume and compression ratio
• Precision 4.080 inch bore diameter for exact fitment in Chrysler 6.1L HEMI cylinders
• 1.080 inch compression height tailored for shelf stock configurations
• 0.866 inch wrist pin diameter for robust piston-to-rod connection
• Supplied as a complete set of eight pistons with premium piston rings included
• Engineered for heavy to severe duty race builds requiring high reliability and performance
• Professional Series quality ensures consistent manufacturing tolerances and balanced components

Construction & Design:

These pistons are crafted from high-grade forged aluminum alloy, providing an excellent strength-to-weight ratio essential for racing applications. The forging process enhances grain structure and fatigue resistance, allowing the pistons to withstand high cylinder pressures and temperatures.

The -28cc dish design helps control compression ratio and combustion characteristics, making it suitable for forced induction or naturally aspirated race engines. The pistons are precision machined to tight tolerances, ensuring optimal ring sealing and minimal friction for improved efficiency and durability.

Installation & Fitment:

This piston kit is designed as a direct replacement for the Chrysler 6.1L 3rd Gen HEMI engine, matching OEM specifications for bore size, compression height, and pin diameter. Installation requires standard engine assembly procedures and is intended for professional engine builders or experienced enthusiasts.

No modifications to the engine block or connecting rods are typically necessary when using this kit, provided the engine is prepared to factory specifications. Proper ring end gap and piston clearance measurements should be verified during assembly.
