• 6.200-inch rod length optimized for ideal piston-to-rod ratio and engine geometry
• 0.945-inch wrist pin diameter for enhanced durability and reduced flex under high loads
• 1.280-inch compression height engineered for precise piston-to-deck clearance and optimal combustion chamber volume
• Includes premium piston rings installed to ensure excellent sealing and reduced blow-by
• Reinforced ring lands and skirt profiles designed to reduce friction and wear during high-RPM operation
• Built to withstand heavy-duty racing environments and high-boost forced induction setups

Construction & Design

Wiseco’s Professional Series pistons are manufactured using state-of-the-art forging techniques that create a dense, uniform grain structure for maximum strength and fatigue resistance. The forged aluminum alloy construction balances lightweight design with high tensile strength, essential for handling the extreme pressures and temperatures generated by high-performance Hellcat and Demon engines.

Each piston is precision-machined to exacting tolerances, ensuring consistent fitment and optimal performance. The design features reinforced ring lands and optimized skirt profiles to minimize friction and wear, contributing to longer piston life and improved engine efficiency under severe duty conditions.

Installation & Fitment

This piston set is a direct-fit replacement for Chrysler Gen 3 6.2L HEMI Hellcat and Demon engines installed in 2015–2024 Dodge Challenger, Charger, Durango Hellcat models, and Ram 1500 TRX. Installation follows standard engine assembly procedures and is recommended for professional engine builders or experienced enthusiasts.

No modifications to the engine block or connecting rods are necessary when using these pistons, provided the engine is built to factory or compatible specifications. Proper ring end gap and clearance checks should be performed during assembly to ensure optimal sealing and reliability.
