Construction & Design

Each piston is forged using Wiseco’s advanced forging process, which enhances the aluminum alloy’s grain structure to maximize strength and fatigue resistance. The pistons feature a carefully engineered dish volume of -11.5cc, optimizing compression and combustion efficiency specifically for the Gen III HEMI platform. Compatibility with a 6.200-inch connecting rod length ensures proper piston-to-rod geometry, reducing piston slap and improving overall engine reliability.

The robust 0.945-inch wrist pin diameter provides a strong connection capable of handling high RPM and high load conditions typical in racing and performance applications. Precision machining to OEM specifications guarantees seamless integration with factory cylinder bores and rods when matched correctly.

Installation & Fitment

This piston set is a direct fit replacement for Chrysler Gen III 6.4L HEMI engines from 2011 to 2024, including models such as the Chrysler 300, Dodge Challenger, Charger, Durango, Jeep Grand Cherokee, Wrangler, Ram 2500, Ram 3500, and Jeep Grand Wagoneer. Installation is straightforward for experienced engine builders, requiring no modifications to the engine block or rods when the correct bore and rod sizes are used.

Professional installation and adherence to proper engine assembly practices are recommended to ensure maximum performance and durability.
