• Forged from aerospace-grade aluminum alloy for superior strength and thermal resistance
• +21cc dome design to increase compression ratio and improve combustion efficiency
• 1.205-inch compression height tailored for shelf stock configurations to maintain proper piston-to-deck clearance
• 3.937-inch bore size compatible with Chrysler 5.7L 3rd Gen HEMI engine blocks
• 0.927-inch wrist pin diameter for a robust pin-to-piston connection and reduced wear
• Includes premium piston rings engineered for optimal sealing and reduced blow-by
• Designed to withstand heavy to severe duty race builds, supporting high RPM and boost levels
• Precision CNC machining ensures tight tolerances and consistent fitment
• Optimized dome shape enhances combustion chamber dynamics for improved power and efficiency

Construction & Design

Wiseco’s Professional Series pistons are forged using aerospace-grade aluminum alloy, providing an excellent strength-to-weight ratio essential for high-performance engines. The forging process refines the grain structure, resulting in pistons that resist cracking and deformation under extreme heat and mechanical stress.

The +21cc dome design is carefully engineered to increase compression without compromising piston integrity or clearance. With a compression height of 1.205 inches, these pistons maintain proper deck height and ring seal in shelf stock configurations. CNC machining to exact specifications ensures consistent dimensions and surface finishes that promote ring sealing and reduce friction.

The robust 0.927-inch wrist pin diameter further enhances durability by minimizing pin deflection during high-load operation, making these pistons ideal for demanding race and performance applications.

Installation & Fitment

This piston set is a direct fit for Chrysler 5.7L 3rd Generation HEMI engines with a 3.937-inch bore, covering a wide range of vehicles from 2003 to 2024 including Chrysler 300 and 300C, Dodge Challenger, Charger, Dakota, Durango, Magnum, Ram trucks, and Jeep Commander, Grand Cherokee, and Wagoneer models.

Installation follows standard engine assembly procedures. Precise measurements are required to ensure proper piston-to-cylinder wall clearance and ring end gaps. No modifications to the engine block or connecting rods are typically necessary when using these pistons in compatible builds.

What's Included
