Overview

The Wiseco Professional Series Piston is engineered for serious racers and high-performance builders who demand uncompromising strength and reliability. Designed specifically for the 6.1L SRT8 engines found in select Chrysler, Dodge, and Jeep models from 2005 to 2010, these forged pistons deliver exceptional durability under heavy and severe duty race conditions. Featuring a -15cc reverse dome design and a 4.060-inch bore size, they provide precise combustion chamber volume control to optimize power and efficiency.

Wiseco’s Professional Series pistons come equipped with premium piston rings and incorporate advanced manufacturing techniques to ensure maximum performance and longevity. Whether you’re building a track-focused race engine or a high-output street machine, these pistons remove the limits of conventional components and elevate your build to professional standards.

Key Features

Wiseco Professional Series pistons combine cutting-edge technology with race-proven design elements to meet the demands of extreme engine builds. Key features include:

• Forged 2618 aluminum alloy construction for superior strength and fatigue resistance
• -15cc reverse dome design to optimize compression ratio and combustion efficiency
• 4.060-inch bore diameter tailored for precise fitment in 6.1L SRT8 engines
• Premium piston rings included for enhanced sealing and reduced blow-by
• Custom-machined skirt profiles to reduce friction and improve ring seal
• Heat-treated and shot-peened surfaces for improved durability and crack resistance
• Designed for heavy to severe duty racing applications, including drag, road course, and endurance racing
• Compatible with high-boost forced induction and nitrous oxide setups

Construction & Design

Each Wiseco Professional Series piston is crafted from high-grade 2618 forged aluminum alloy, known for its excellent strength-to-weight ratio and resistance to thermal fatigue. The forging process ensures a dense, uniform grain structure that withstands the extreme pressures and temperatures encountered in racing environments.

The reverse dome design reduces combustion chamber volume by 15cc, allowing engine builders to fine-tune compression ratios for maximum power output and efficiency. Precision CNC machining guarantees tight tolerances and consistent piston geometry, while advanced surface treatments enhance wear resistance and reduce friction.

Installation & Fitment

These pistons are designed as direct replacements for factory components in the specified 6.1L SRT8 engines. Installation requires standard engine assembly procedures, including proper ring end gap setting and piston orientation. Due to their race-grade construction, it is recommended that installation be performed by experienced engine builders or professionals to ensure optimal performance and reliability.

They fit the following vehicles:

• 2005–2010 Chrysler 300C 6.1L SRT8
• 2006–2010 Dodge Charger 6.1L SRT8
