• Compression height of 1.110 inches for optimal piston-to-cylinder head clearance and combustion efficiency.
• Pin diameter of 0.866 inches, engineered for durability and precise fitment.
• Supplied with premium piston rings designed to maintain excellent sealing under extreme conditions.
• Custom-level performance features tailored for heavy to severe duty race engines.
• Designed to handle the high cylinder pressures and temperatures typical of forced induction setups like Hellcat and Demon engines.
• Set of 8 pistons, ideal for complete engine builds or rebuilds.

Construction & Design:

Each piston in this Professional Series set is forged from high-grade alloy material, providing superior tensile strength and fatigue resistance compared to cast pistons. The forging process ensures a dense, uniform grain structure that enhances durability under extreme racing conditions.

The pistons feature a carefully engineered compression height and pin diameter to maintain precise geometry and optimal piston-to-cylinder wall clearance. This attention to detail helps improve combustion efficiency and reduces the risk of piston slap or premature wear.

Wiseco’s commitment to quality includes supplying these pistons with premium rings, ensuring excellent sealing and reduced blow-by, which is critical for maintaining power and engine longevity in high-performance applications.

Installation & Fitment:

This piston set is designed as a direct fit for Chrysler 6.2L Gen3 HEMI engines found in Hellcat and Demon models. The dimensions and specifications match factory and performance rebuild requirements, making installation straightforward for experienced engine builders.

Proper engine assembly practices and clearances should be followed to ensure optimal performance and reliability. No modifications to the block or additional machining beyond standard rebuild procedures are typically required.
