Part #: K0105X1

Overview

The Wiseco Professional Series Forged Piston Set is engineered specifically for the Chrysler 5.7L 3rd Generation HEMI V8 engine, covering model years 2003 through 2024. Designed for high-performance builders and serious racers, this piston kit delivers exceptional strength and durability to withstand heavy to severe duty applications. Whether you are assembling a dedicated race engine or a high-output street machine, these pistons provide the reliability and precision fitment necessary to exceed factory performance limits.

Featuring a +6.5cc dome volume and a 3.927-inch bore size, this piston set optimizes combustion efficiency and power potential, making it an ideal upgrade for forced induction or naturally aspirated builds. Wiseco’s Professional Series pistons are crafted to support high-RPM operation and demanding conditions, ensuring your engine performs consistently at its peak.

Key Features

Wiseco’s Professional Series forged pistons incorporate advanced materials and design innovations to meet the rigorous demands of performance engines:

• Forged from premium-grade aluminum alloy for superior strength and excellent heat resistance under extreme conditions.
• +6.5cc dome design increases compression ratio, enhancing power output and throttle response.
• Precisely sized 3.927-inch bore tailored for Chrysler 5.7L 3rd Gen HEMI applications, ensuring exact cylinder fitment.
• 1.220-inch compression height optimized for ideal piston-to-cylinder head clearance and ring sealing.
• 0.945-inch wrist pin diameter engineered for durability and reduced reciprocating mass.
• Includes premium piston rings matched to piston specifications for excellent sealing and reduced blow-by.
• Manufactured to exacting tolerances for consistent performance and reliability in race environments.
• Durable skirt coating reduces friction and wear, extending engine life under demanding conditions.
• Ideal for heavy-duty, high-RPM, and forced induction engine builds requiring robust piston construction.

Construction & Design

Each piston is forged using Wiseco’s advanced manufacturing processes, resulting in a dense, uniform grain structure that enhances fatigue resistance and thermal conductivity. The +6.5cc dome shape is carefully engineered to optimize combustion chamber dynamics, promoting efficient flame propagation and improved power delivery.

Precision machining ensures perfect ring groove dimensions and pin bore alignment, critical for maintaining engine integrity during high-stress operation. The pistons also feature a durable skirt coating that minimizes friction and wear, contributing to longer engine life and consistent performance in severe duty applications.

Installation & Fitment

This piston kit is designed as a direct replacement for the Chrysler 5.7L 3rd Gen HEMI engine, fitting the factory bore size with a slight overbore to 3.927 inches. Installation requires professional engine assembly practices, including proper cylinder honing and ring fitting. No modifications to the engine block or other components are necessary beyond standard machining procedures.

The set includes eight pistons for a complete V8 engine rebuild and is compatible with factory connecting rods and wrist pins matching the 0.945-inch pin diameter. These pistons are recommended for race or high-performance builds that demand forged piston strength and reliability.
