Key Features

Wiseco’s Professional Series pistons incorporate advanced materials and precision manufacturing to meet the demands of high-performance applications:

• Forged from premium-grade aluminum alloy for superior strength and resistance to cracking or deformation under high heat and pressure.
• Flat top piston design with a -2cc dish volume to optimize compression ratio and combustion efficiency.
• Compression height of 1.090 inches engineered for precise deck clearance and optimal piston-to-head geometry.
• 3.917-inch bore diameter and 4.050-inch stroke matching factory specifications for the Chrysler 5.7L HEMI engine.
• 0.927-inch wrist pin diameter providing robust pin support and reduced wear during high RPM operation.
• Complete set of 8 pistons for full V8 engine rebuilds.
• Includes premium piston rings designed to maintain excellent sealing and minimize blow-by under racing conditions.
• Built to withstand heavy to severe duty race environments, including boosted and high-RPM applications.

Construction & Design

Each piston in this kit is meticulously forged from high-quality aluminum alloy, delivering superior strength compared to traditional cast pistons. This construction resists cracking and deformation even under extreme thermal and mechanical stress encountered in racing and high-performance driving.

The flat top design with a slight volume reduction (-2cc) is engineered to optimize the engine’s compression ratio, enhancing power output and combustion stability. Precision CNC machining ensures tight tolerances for excellent ring sealing and piston-to-cylinder wall fitment, which improves overall engine efficiency and durability.

Installation & Fitment

This piston set is a direct replacement for the Chrysler 5.7L HEMI engine, designed to fit engines requiring a 3.917-inch bore and 4.050-inch stroke with a 1.090-inch compression height. Installation follows standard engine assembly procedures without the need for block modifications or additional machining beyond typical honing.

The kit is compatible with factory wrist pins and connecting rods matching the 0.927-inch pin diameter, allowing for straightforward installation in 2003–2024 Chrysler 300, 300C, Dodge Challenger, Charger, Dakota, Durango, Magnum, Ram 1500/2500/3500, Jeep Commander, Grand Cherokee, and Wagoneer models equipped with the 5.7L HEMI engine.
