Key Features:

Wiseco’s Professional Series pistons incorporate advanced design and manufacturing techniques to ensure maximum performance and reliability:

• Forged from high-strength aluminum alloy for superior durability and resistance to thermal and mechanical stress.
• 4.055 inch bore size tailored for the Chrysler 6.1L HEMI engine to maintain optimal cylinder sealing and combustion efficiency.
• 8cc reverse dome (R/Dome) design to optimize compression ratio and combustion chamber shape for improved power output.
• 1.220 inch compression height engineered to match stock piston shelf dimensions for proper ring placement and piston-to-cylinder clearance.
• 0.984 inch wrist pin diameter for enhanced pin strength and reduced piston rocking under high loads.
• Professional Series pistons come equipped with premium piston rings to ensure excellent sealing and reduced blow-by.
• Right side piston configuration designed to fit precisely in the intended cylinder location for balanced engine operation.
• Ideal for heavy-duty race builds requiring components that withstand extreme RPM, heat, and pressure.

Construction & Design:

Each piston is meticulously forged using state-of-the-art processes to achieve a dense, uniform grain structure that enhances strength and fatigue resistance. The reverse dome shape is CNC-machined to exact specifications, ensuring consistent combustion chamber volume and efficient flame propagation.

The piston’s compression height and bore dimensions are engineered to match the Chrysler 6.1L HEMI’s factory specifications, allowing for seamless integration with existing engine components without the need for extensive modifications. The robust wrist pin diameter further contributes to durability under high-stress conditions commonly encountered in racing environments.

Installation & Fitment:

This Wiseco Professional Series piston is designed as a direct replacement for the right side piston in the Chrysler 6.1L 3rd Gen HEMI engine. It fits stock piston shelves and maintains factory compression height, ensuring proper ring end gap and piston-to-wall clearance.

Installation requires standard engine assembly procedures. No special modifications, cutting, or tuning are necessary beyond typical race engine build practices.

• Direct fit for Chrysler 6.1L 3rd Gen HEMI right side piston position
• Compatible with factory piston shelf dimensions
• Requires professional engine assembly and ring fitting
