• 1.110-inch compression height optimized for proper piston-to-cylinder head clearance and combustion chamber volume.
• 0.927-inch pin diameter for enhanced wrist pin strength and durability under high loads.
• 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 in racing conditions.
• Designed to withstand the rigors of heavy-duty and severe race environments, including boosted and high-RPM applications.
• Custom-level performance features that support increased horsepower and torque without sacrificing reliability.

Construction & Design:

Wiseco’s Professional Series pistons are crafted using state-of-the-art forging processes that enhance grain structure and mechanical properties. The forged aluminum alloy construction offers a perfect balance of lightweight design and exceptional strength, helping to reduce reciprocating mass and improve engine response.

Each piston is precision-machined to exacting tolerances to ensure consistent fitment and optimal performance. The compression height and pin diameter are carefully selected to match the Chrysler 6.4L Gen3 HEMI engine architecture, ensuring proper piston-to-cylinder head clearance and wrist pin fitment.

These pistons are built to endure the extreme conditions of racing, including high cylinder pressures, elevated temperatures, and aggressive driving styles, making them a reliable choice for serious performance builds.

Installation & Fitment:

This piston set is designed specifically for Chrysler 6.4L Gen3 HEMI engines, including Hellcat and Demon models. Installation requires standard engine assembly procedures and is intended for professional or experienced engine builders.

Ensure proper ring end gap and piston orientation during installation to maximize performance and longevity. No modifications to the engine block or cylinder bore are required beyond standard machining and honing practices.
