Wiseco Professional Series Forged Pistons

Chrysler 5.7L 3rd Gen HEMI V8

K0036X2

Overview:

The Wiseco Professional Series forged piston set is engineered specifically for serious racers and high-performance builders who demand uncompromising strength and durability. Designed for the Chrysler 5.7L 3rd Generation HEMI engine, these pistons are ideal for heavy to severe duty race applications where reliability under extreme conditions is critical.

Each piston is precision forged and crafted to exacting standards, delivering superior performance and longevity compared to stock cast pistons. Whether you are building a race motor or a high-output street engine, these pistons provide the foundation to push your build beyond factory limits.

With a -10cc reverse dome design and a compression height of 1.205 inches, this set optimizes combustion chamber volume and piston-to-valve clearance for enhanced efficiency and power potential.

Key Features:

Wiseco’s Professional Series pistons incorporate advanced materials and design features to meet the demands of high-performance engines:

• Forged from premium-grade aluminum alloy for maximum strength and fatigue resistance.
• 10cc reverse dome piston crown design improves combustion efficiency and helps control detonation.
• Compression height of 1.205 inches ensures proper deck clearance and ring seal for the 3.937-inch bore.
• Pin diameter of 0.927 inches engineered for durability and precise wrist pin fitment.
• Set of 8 pistons, perfect for complete V8 engine builds.
• Includes premium piston rings designed to withstand high cylinder pressures and temperatures.
• Professional Series pistons are built to withstand heavy to severe duty race conditions, including boosted and high-RPM applications.
• Designed to maintain tight tolerances for optimal piston-to-cylinder wall fit and reduced friction.

Construction & Design:

Each piston in this set is forged using Wiseco’s proprietary forging process, which enhances the grain structure of the aluminum alloy for superior strength and durability. The reverse dome (R/Dome) design reduces combustion chamber volume by 10cc, allowing for higher compression ratios and improved power output.

The pistons feature a 1.205-inch compression height tailored to the 3.937-inch bore size of the Chrysler 5.7L HEMI, ensuring precise piston positioning within the cylinder. The 0.927-inch pin diameter provides a robust wrist pin connection, critical for high-RPM and high-load conditions.

Wiseco’s Professional Series pistons are engineered to deliver consistent performance in demanding race environments, with enhanced resistance to thermal and mechanical stresses.

Installation & Fitment:

This piston set is designed as a direct replacement for the Chrysler 5.7L 3rd Gen HEMI engine with a 3.937-inch bore. Proper machining and engine assembly practices are required to ensure optimal fit and performance.

These pistons are intended for professional engine builders and racers familiar with high-performance engine assembly. No cutting or modification of the pistons is necessary when installed in compatible engine blocks.

• Fits Chrysler 5.7L 3rd Gen HEMI V8 engines with 3.937-inch bore.
• Requires compatible connecting rods and wrist pins matching the 0.927-inch pin diameter.
• Installation should be performed by experienced engine builders to ensure proper clearances and ring end gaps.
