Overview:

The Wiseco Professional Series forged racing pistons are engineered for serious racers and high-performance builders who demand uncompromising strength and reliability. Designed specifically for the Chrysler 5.7L 3rd Generation HEMI engine, these pistons provide a robust foundation for heavy to severe duty race applications.

Whether you are building a dedicated race engine or a high-output street performance motor, these pistons deliver the durability and precision required to handle increased cylinder pressures and aggressive tuning. With premium rings included, you’ll get a complete piston set that supports enhanced combustion efficiency and long-term engine durability.

Key Features:

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

• Forged from high-strength aluminum alloy for superior durability under extreme conditions.
• +6.55cc dome volume to optimize compression ratio and combustion characteristics.
• 1.220 inch compression height tailored for the Chrysler 5.7L HEMI to maintain proper piston-to-head clearance.
• 3.937 inch bore size, matching factory cylinder dimensions for precise fitment.
• 0.945 inch wrist pin diameter engineered for strength and reduced reciprocating mass.
• Professional Series pistons include premium piston rings for enhanced sealing and reduced blow-by.
• Designed to withstand the rigors of heavy-duty racing and high-performance street use.
• Manufactured with tight tolerances to ensure consistent piston weight and balance across the set.

Construction & Design:

Wiseco’s Professional Series pistons are crafted using state-of-the-art forging processes that produce a dense, uniform grain structure for maximum strength. The dome design increases combustion chamber volume, allowing for optimized compression ratios that improve power output without sacrificing reliability.

Each piston is precision-machined to exact specifications, ensuring perfect fitment in the Chrysler 5.7L HEMI cylinders. The forged aluminum alloy construction offers excellent thermal conductivity and resistance to detonation, making these pistons ideal for race engines subjected to high boost or nitrous applications.
