Construction & Design:

Wiseco’s Professional Series pistons are manufactured using high-grade forged aluminum alloy, providing an excellent strength-to-weight ratio. The forging process enhances the metal’s grain structure, resulting in pistons that withstand the intense pressures and temperatures of racing environments.

The +12cc dome shape is precision-machined to optimize combustion chamber volume, improving power output and efficiency when paired with compatible cylinder heads. The pistons feature a compression height of 1.090 inches, perfectly matched to the 4.050 inch stroke and 3.927 inch bore of the Chrysler 5.7L HEMI, ensuring proper piston-to-cylinder clearance and ring seal.

Installation & Fitment:

This piston kit is designed as a direct replacement for the Chrysler 5.7L 3rd Generation HEMI engine. It fits the factory bore size of 3.927 inches and is compatible with the stock stroke of 4.050 inches. Installation requires standard engine assembly procedures and proper ring end gap setting.

These pistons are intended for professional engine builders and racers familiar with high-performance engine assembly. No modifications to the engine block or other components are typically necessary when installing this kit, provided the engine is prepared to factory specifications.

What's Included:

• Set of 8 forged pistons with +12cc dome design
• Premium piston rings pre-installed or included for each piston
• All pistons feature 0.927 inch wrist pin diameter

Ideal For:
