Wiseco Professional Series Forged Pistons

Chrysler Gen 3 6.4L HEMI V8

K0397X1

Overview:

The Wiseco Professional Series forged piston set is engineered specifically for high-performance applications in Chrysler’s 6.4L Gen 3 HEMI engines. Designed with serious racers and engine builders in mind, these pistons deliver exceptional strength and durability to withstand the rigors of heavy to severe duty race builds. Whether you are building a track-focused machine or a high-output street engine, these pistons provide the reliability and performance needed to push your build beyond factory limits.

Each set includes eight pistons with a 4.100-inch bore diameter and a 1.210-inch compression height, optimized for the Chrysler 6.4L HEMI platform. The Professional Series pistons come complete with premium piston rings, ensuring a precise fit and enhanced sealing for improved combustion efficiency and power delivery.

Key Features:

Wiseco’s Professional Series pistons incorporate advanced design and manufacturing techniques to meet the demands of high-performance and racing environments. Key features include:

• Forged construction from high-strength aluminum alloy for superior durability and resistance to thermal and mechanical stress.
• Precision CNC machining to exact tolerances, ensuring consistent bore fit and optimal piston-to-cylinder wall clearance.
• 1.210-inch compression height tailored for the Chrysler 6.4L HEMI to maintain proper deck clearance and piston-to-valve clearance.
• 0.927-inch wrist pin diameter for enhanced pin strength and reduced piston pin deflection under high loads.
• Supplied with premium piston rings designed for improved sealing, reduced blow-by, and enhanced oil control.
• Optimized piston crown design to support efficient combustion and high compression ratios typical of performance HEMI engines.
• Engineered for use in heavy-duty race builds, including drag racing, road racing, and other motorsport applications requiring maximum reliability.
• Compatible with factory and aftermarket components designed for the Chrysler Gen 3 6.4L HEMI platform.

Construction & Design:

These pistons are forged from a premium aluminum alloy selected for its excellent strength-to-weight ratio and thermal conductivity. The forging process enhances grain structure, providing superior fatigue resistance compared to cast pistons. CNC machining ensures each piston meets strict dimensional specifications, critical for maintaining engine reliability and performance at high RPMs.

The piston design incorporates a robust pin boss and wrist pin diameter to handle the increased loads encountered in racing environments. The compression height is carefully matched to the 6.4L HEMI’s cylinder geometry, ensuring proper piston positioning within the combustion chamber for optimal power and efficiency.

Installation & Fitment:

This piston set is designed as a direct replacement for the Chrysler Gen 3 6.4L HEMI engine, fitting a 4.100-inch bore. Installation requires standard engine assembly procedures, including proper honing and cleaning of the cylinder bores. The pistons are compatible with factory connecting rods and wrist pins sized for the 0.927-inch pin diameter.

No modifications to the engine block or other components are necessary when installing this piston set, provided the engine is prepared to the correct specifications. Professional engine assembly and balancing are recommended to maximize performance and longevity.

What's Included:

• Set of 8 forged pistons, 4.100-inch bore diameter
• Premium piston rings pre-installed or included
• All pistons feature 1.210-inch compression height and 0.927-inch wrist pin diameter
