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.

Installation & Fitment:

This piston set is designed as a direct replacement for the Chrysler 5.7L 3rd Gen HEMI engine, matching OEM bore and compression height specifications. Installation requires standard engine assembly procedures and is intended for experienced builders or professional engine shops.
