Key Features

Wiseco’s Professional Series pistons incorporate advanced materials and design features to deliver superior performance and durability:

• Forged from high-strength aluminum alloy for enhanced resistance to thermal and mechanical stress
• Precisely machined to a 4.100-inch bore diameter, matching Chrysler 6.4L Gen III HEMI specifications
• Compression height of 1.210 inches for accurate piston-to-cylinder head clearance and combustion chamber volume
• 0.945-inch wrist pin diameter for increased pin strength and reduced flex under high loads
• Negative 11.5cc piston volume to optimize compression ratio and combustion characteristics
• Engineered to resist detonation and wear in heavy-duty race environments
• Includes premium piston rings designed to maintain excellent sealing and minimize blow-by
• Complete set of 8 pistons, perfect for full V8 engine rebuilds

Construction & Design

Wiseco’s Professional Series pistons are manufactured using advanced forging techniques that ensure a uniform grain structure and maximum strength. The forged aluminum alloy construction strikes an ideal balance between lightweight design and toughness, reducing reciprocating mass to improve throttle response and engine efficiency.

Each piston is engineered with precise compression height and wrist pin dimensions to maintain proper geometry within the Chrysler Gen III HEMI platform. This precision supports consistent combustion chamber volume and optimal piston-to-valve clearance, critical for high-revving race engines and severe duty applications.
