Chrysler 5.7L 3rd Gen HEMI V8

K0036X05

Overview:

The Wiseco Professional Series forged piston kit is engineered specifically for high-performance Chrysler 5.7L 3rd Generation HEMI engines. Designed with serious racers and engine builders in mind, these pistons deliver exceptional strength and durability for heavy to severe duty race applications. Whether you are building a track-focused machine or a high-output street engine, this piston kit provides the reliability and performance needed to push your build beyond factory limits.

Each piston is precision forged from premium materials and comes complete with high-quality rings, ensuring optimal sealing and longevity under extreme conditions. With a -10cc reverse dome design and a compression height of 1.205 inches, these pistons are tailored to enhance combustion efficiency and support aggressive tuning strategies.

Key Features:

Wiseco’s Professional Series pistons incorporate advanced design and manufacturing techniques to meet the demands of serious performance enthusiasts:

• Forged construction for superior strength and resistance to detonation compared to cast pistons.
• 10cc reverse dome (R\Dome) design to optimize combustion chamber shape and compression ratio.
• Compression height of 1.205 inches, engineered for precise piston-to-cylinder head clearance and optimal ring positioning.
• 3.922 inch bore size, matching the Chrysler 5.7L HEMI specifications for a perfect fit.
• 0.927 inch wrist pin diameter for enhanced pin strength and durability under high loads.
• Set of 8 pistons, suitable for complete V8 engine builds.
• Includes premium piston rings designed for high-performance sealing and wear resistance.
• Ideal for heavy-duty race builds, including drag racing, road racing, and other motorsport applications.

Construction & Design:

Each piston in this kit is crafted using Wiseco’s renowned forging process, which produces a dense, uniform grain structure for maximum toughness. The reverse dome shape helps lower the compression ratio slightly, allowing for increased boost or aggressive ignition timing without risking detonation. The pistons feature a precision-machined skirt and ring lands to reduce friction and improve ring seal, contributing to better power output and engine efficiency.

The 0.927 inch pin diameter enhances wrist pin stability, reducing the risk of pin failure under high RPM and load conditions. This piston kit is engineered to exacting tolerances to ensure consistent performance and reliable fitment in Chrysler’s 5.7L HEMI engines.

Installation & Fitment:

This piston kit is designed as a direct replacement for Chrysler 5.7L 3rd Gen HEMI engines, requiring no modifications to the block or connecting rods when installed correctly. It is intended for professional engine builders and racers familiar with high-performance engine assembly procedures. Proper ring end gap and piston-to-wall clearance should be verified during installation to ensure optimal performance and longevity.

What’s Included
