Key Features:

These pistons incorporate advanced design and manufacturing techniques to ensure maximum performance and longevity:

• Forged from high-strength aluminum alloy for superior durability and heat resistance.
• Precision-machined to a 4.095-inch bore size, matching Gen3 HEMI specifications.
• Compression height of 1.110 inches optimized for proper deck clearance and piston-to-valve clearance.
• Pin diameter of 0.866 inches designed for compatibility with factory and aftermarket connecting rods.
• Supplied as a complete set of 8 pistons, ideal for V8 engine builds.
• Includes premium piston rings engineered to maintain excellent sealing and reduce blow-by.
• Professional Series pistons are built to withstand the rigors of heavy-duty racing and high-boost applications.
• Designed to support increased horsepower and torque outputs typical of modified Hellcat and Demon engines.

Construction & Design:

Wiseco’s Professional Series pistons are crafted using state-of-the-art forging processes that enhance grain structure and mechanical properties. This results in pistons that resist cracking, scuffing, and thermal fatigue even under the most demanding conditions.

The pistons feature a carefully engineered compression height and pin diameter to ensure precise fitment and optimal piston-to-cylinder wall clearance. This attention to detail helps maintain engine reliability and performance during extended high-RPM operation.

Each piston is finished with tight tolerances and balanced for smooth engine operation, contributing to reduced vibration and improved overall drivetrain longevity.

Installation & Fitment:

This piston set is designed as a direct replacement for Chrysler 6.4L Gen3 HEMI engines, including Hellcat and Demon models. Installation requires standard engine rebuild procedures and is compatible with factory connecting rods and components matching the specified dimensions.

No special modifications to the engine block or rods are necessary when using these pistons, provided the engine is prepared to OEM or performance rebuild standards.

• Direct fit for Chrysler 6.4L Gen3 HEMI Hellcat and Demon engines
