Part #: K468XS

Overview

The Wiseco Professional Series Forged Piston Set is engineered specifically for the Chrysler 5.7L 3rd Generation HEMI V8 engines from 2003 through 2024. Designed for serious racers and high-performance engine builders, this piston set delivers exceptional strength, durability, and reliability under heavy to severe duty conditions. Whether you are assembling a high-output street machine or a dedicated race car, these pistons provide the enhanced compression and robust construction needed to maximize power and withstand elevated cylinder pressures.

Featuring a +12cc dome design and a precise 1.080-inch compression height, these pistons optimize combustion efficiency and power potential while maintaining compatibility with factory bore dimensions and engine geometry. This set of eight forged pistons is a direct replacement for stock components, making it ideal for complete V8 rebuilds targeting improved performance and longevity.

Key Features

Wiseco’s Professional Series pistons incorporate advanced materials and precision engineering to meet the demands of high-performance and racing applications. Key features include:

• Forged from premium-grade aluminum alloy for superior strength and heat resistance
• +12cc dome design to increase compression ratio and improve combustion efficiency
• 1.080-inch compression height tailored for the Chrysler 5.7L 3rd Gen HEMI architecture
• 3.917-inch bore size matching factory cylinder dimensions for precise fitment
• 0.866-inch pin diameter for robust wrist pin support and durability
• Designed to withstand high cylinder pressures and temperatures in severe duty race builds
• Includes premium piston rings engineered for optimal sealing and reduced friction
• Manufactured with tight tolerances to ensure consistent performance and reliability
• Stock-style shelf configuration for compatibility with existing engine components

Construction & Design

Wiseco’s Professional Series pistons are crafted using state-of-the-art forging techniques that enhance the aluminum alloy’s grain structure and mechanical properties. This process produces pistons that are significantly stronger and more fatigue-resistant than traditional cast pistons, making them ideal for high-stress racing environments.

The +12cc dome increases combustion chamber volume, allowing builders to raise compression ratios for improved power output without compromising engine reliability. The pistons maintain a stock compression height and wrist pin diameter to preserve proper piston-to-rod geometry and engine balance, minimizing the need for extensive modifications during installation.

Installation & Fitment

This piston set is designed as a direct replacement for the Chrysler 5.7L 3rd Gen HEMI engine, fitting the factory bore size and compression height specifications precisely. Installation requires standard engine rebuild procedures, including machining and honing of the cylinder bores. It is recommended that installation be performed by experienced technicians to ensure proper clearances and ring end gaps.

The set includes eight pistons compatible with stock connecting rods and wrist pins matching the specified 0.866-inch pin diameter. No modifications to the engine block or cylinder bore beyond standard rebuild practices are necessary.

What's Included
