• Compression height of 1.110 inches optimized for exact piston-to-cylinder fitment
• 0.927 inch wrist pin diameter for enhanced pin strength and stability under high loads
• Complete set of eight pistons ideal for V8 engine builds
• Includes premium piston rings engineered for optimal sealing and reduced friction
• Reinforced pin bosses and ring lands resist cracking and wear during high-RPM operation
• Durable friction-reducing coating extends engine life under demanding conditions
• Built to withstand heavy-duty racing and high-boost applications

Construction & Design

Wiseco Professional Series pistons are manufactured using state-of-the-art forging processes that enhance the metal grain structure, resulting in maximum strength and durability. Each piston is precision-machined to exact tolerances, ensuring consistent fitment and performance across all cylinders. The forged aluminum construction offers an excellent strength-to-weight ratio, reducing reciprocating mass and improving engine responsiveness.

Reinforced areas around the pin bosses and ring lands provide additional resistance to cracking and wear, even under extreme high-RPM conditions. A specialized coating reduces friction and protects against scuffing, helping to extend the life of your engine components during severe duty operation.

Installation & Fitment

This piston set is designed for direct fitment in Chrysler 6.4L Gen3 HEMI engines, including Hellcat and Demon models, covering model years 2011 through 2024 across multiple platforms such as Chrysler 300, Dodge Challenger, Charger, Durango, Jeep Grand Cherokee, Wrangler, Ram 2500, Ram 3500, and Jeep Grand Wagoneer. Installation follows standard engine assembly procedures and is recommended for professional engine builders or experienced enthusiasts.

No modifications to the engine block or additional machining beyond typical rebuild practices are generally required. Proper ring end gap and clearance checks should be performed to ensure optimal performance and longevity. These pistons are compatible with factory connecting rods and wrist pins matching the specified 0.927 inch pin diameter.
