Wiseco Professional Series Forged Pistons

Chrysler 5.7L 3rd Gen HEMI V8

K467X2

Overview:

The Wiseco Professional Series forged pistons are precision-engineered components designed specifically for serious racers and high-performance engine builders. Crafted with no expense spared, these pistons deliver exceptional strength and durability to withstand the demands of heavy to severe duty race applications.

Ideal for enthusiasts upgrading or rebuilding Chrysler 5.7L 3rd Generation HEMI engines, this piston set offers enhanced combustion efficiency and reliability. With a +21cc dome design and a 1.205-inch compression height, these pistons help optimize compression ratios for improved power output and engine response.

Each set includes premium rings and is built to exacting tolerances, ensuring consistent performance and long-lasting durability under extreme conditions. Whether you are building a dedicated race engine or a high-performance street machine, Wiseco’s Professional Series pistons provide the foundation for removing limits and achieving your performance goals.

Key Features:

These pistons incorporate advanced design and manufacturing features to meet the rigorous demands of racing and high-performance builds:

• Forged from high-strength aluminum alloy for superior durability and resistance to thermal and mechanical stress.
• +21cc dome design to increase compression ratio and improve combustion efficiency.
• 1.205-inch compression height tailored for shelf stock configurations, ensuring 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 robust pin-to-piston connection and reduced wear.
• Professional Series pistons include premium piston rings engineered for optimal sealing and reduced blow-by.
• Designed for 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 from aerospace-grade aluminum alloy, providing an excellent strength-to-weight ratio essential for high-performance engines. The forging process enhances grain structure, resulting in pistons that resist cracking and deformation under extreme heat and pressure.

The +21cc dome design is carefully engineered to increase compression without compromising piston integrity or clearance. The pistons feature a compression height of 1.205 inches, matching shelf stock configurations to maintain proper deck height and ring seal.

Each piston is CNC-machined to exact specifications, ensuring consistent dimensions and surface finishes that promote ring sealing and reduce friction. The robust 0.927-inch wrist pin diameter further contributes to durability by minimizing pin deflection during high-load operation.

Installation & Fitment:

This piston set is designed as a direct fit for Chrysler 5.7L 3rd Generation HEMI engines with a 3.937-inch bore. It is intended for professional engine builders and racers who require high-performance components for severe duty applications.

Installation requires standard engine assembly procedures and precise measurements 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.
