Chrysler 5.7L 3rd Gen HEMI V8

K466XS

Overview:

The Wiseco Professional Series forged piston kit is engineered for serious racers and high-performance builders who demand uncompromising strength and durability. Designed specifically for the Chrysler 5.7L 3rd Generation HEMI V8 engine, this set of eight pistons offers a +4cc dome design with a 1.205-inch compression height, perfectly matching shelf stock configurations for optimal fitment and performance.

Whether you are building a heavy-duty race engine or a high-output street machine, these pistons provide the reliability and precision needed to push your build to the next level. Each piston is crafted to withstand severe duty conditions, making them ideal for motorsports and performance applications where durability is critical.

With premium rings included, the Wiseco Professional Series pistons help you maximize power output while maintaining excellent sealing and longevity under extreme operating conditions.

Key Features:

These pistons incorporate advanced design and manufacturing techniques to deliver superior performance and reliability:

• Forged from high-strength aluminum alloy for exceptional durability and resistance to heat and stress.
• +4cc dome design increases compression ratio for improved combustion efficiency and power potential.
• 1.205-inch compression height ensures precise piston-to-cylinder head clearance and optimal quench.
• 0.927-inch pin diameter for robust wrist pin fitment and reduced piston rock.
• Set of 8 pistons engineered specifically for the Chrysler 5.7L 3rd Gen HEMI V8 engine.
• Includes premium piston rings designed for superior sealing and wear resistance in high-performance environments.
• Professional Series pistons are built for heavy to severe duty race builds, offering enhanced fatigue strength and reliability.
• Precision CNC machining ensures consistent dimensions and tight tolerances for excellent engine balance and performance.

Construction & Design:

Wiseco’s Professional Series pistons are forged using state-of-the-art processes that produce a dense, uniform grain structure for maximum strength. The pistons feature a dome shape that increases combustion chamber volume by +4cc, helping to raise compression ratios and improve power output without compromising reliability.

The 1.205-inch compression height is optimized to maintain factory piston-to-deck clearance, ensuring compatibility with stock cylinder heads and minimizing the need for additional machining. The pistons also incorporate a robust pin bore with a 0.927-inch diameter to accommodate heavy-duty wrist pins, reducing wear and enhancing stability under high RPM and load conditions.

Installation & Fitment:

This piston kit is designed as a direct replacement for the Chrysler 5.7L 3rd Gen HEMI engine, matching the factory bore size of 3.917 inches. The pistons fit standard piston shelves and maintain OEM compression height specifications, making installation straightforward for experienced engine builders.

No modifications to the block or cylinder head are typically required when using this kit, provided the engine is prepared to factory specifications. The included premium rings simplify assembly and help ensure proper sealing from the start.
