K0037X05

Overview:

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

If you are building or upgrading a Chrysler 6.1L 3rd Gen HEMI engine, these pistons provide a reliable foundation to push your power limits while maintaining long-term engine integrity. Each set comes complete with premium rings, ensuring optimal sealing and performance right out of the box.

With a bore size of 4.060 inches, a compression height of 1.080 inches, and a pin diameter of 0.866 inches, these pistons are precision-engineered to fit your Chrysler 6.1L HEMI, offering improved strength and durability over stock components.

Key Features:

Wiseco’s Professional Series pistons incorporate advanced materials and design features to support demanding racing environments:

• Forged from high-strength aluminum alloy for superior durability and resistance to high heat and pressure.
• Designed with a -13cc reverse dome (R\Dome) to optimize combustion chamber volume and compression ratio.
• Precision-machined 1.080 inch compression height for accurate piston-to-cylinder fitment.
• 0.866 inch wrist pin diameter for enhanced pin strength and reduced flex under load.
• Includes premium piston rings engineered for excellent sealing and reduced blow-by.
• Ideal for heavy-duty and severe duty race builds requiring maximum reliability and performance.
• Set of 8 pistons, perfect for complete V8 engine rebuilds or upgrades.

Construction & Design:

These pistons are crafted using a professional-grade forging process that enhances the grain structure of the aluminum alloy, resulting in improved strength and fatigue resistance. The reverse dome design helps optimize combustion efficiency and power output by carefully controlling the combustion chamber shape.

Each piston is CNC-machined to exacting tolerances, ensuring consistent compression height and pin bore alignment. This precision manufacturing reduces the risk of piston slap and improves overall engine smoothness and longevity.

Installation & Fitment:

This piston set is designed as a direct fit for Chrysler 6.1L 3rd Gen HEMI engines with a 4.060 inch bore. Installation requires standard engine assembly procedures and is intended for professional or experienced engine builders.

No modifications to the engine block or connecting rods are typically necessary when using these pistons, but proper ring end gap and clearance checks should be performed during assembly.
