Key Features

Wiseco’s Professional Series pistons incorporate advanced engineering and materials to meet the demands of high-performance applications:

• Forged from high-strength aluminum alloy for superior durability and resistance to thermal and mechanical stress
• +5.5 cc dome shape designed to increase compression ratio and improve combustion efficiency
• 4.080-inch bore size with a 1.220-inch compression height tailored for Chrysler 6.1L Gen III HEMI engines
• 0.984-inch pin diameter for precise fitment and enhanced wrist pin strength
• Engineered for heavy to severe duty race builds, ensuring reliability under extreme conditions
• Includes premium piston rings for improved sealing and reduced blow-by
• Set of 8 pistons, perfect for complete V8 engine rebuilds

Construction & Design

These pistons are manufactured using Wiseco’s advanced forging process, which creates a dense, uniform grain structure that significantly enhances strength and fatigue resistance. The forged aluminum alloy construction balances lightweight design with toughness, reducing reciprocating mass to improve engine response and durability.

The precision-machined +5.5 cc dome optimizes combustion chamber shape and volume, supporting higher compression ratios without sacrificing detonation resistance. Tight dimensional tolerances ensure consistent fitment and reliable performance within the Chrysler 6.1L HEMI block.

Installation & Fitment

This piston set is designed as a direct replacement for factory pistons in the 2005–2010 Chrysler 300C, Dodge Challenger, Dodge Charger, Dodge Magnum, and Jeep Grand Cherokee equipped with the 6.1L Gen III HEMI engine. Installation typically requires no modifications to the engine block, but proper engine assembly practices and clearances should be observed to ensure optimal performance and longevity.

The set includes eight pistons, making it ideal for complete V8 engine rebuilds with a 4.080-inch bore.
