The Wiseco Professional Series forged pistons are engineered for serious racers and high-performance engine builders who demand uncompromising strength and reliability. Designed specifically for the Chrysler 6.1L 3rd Generation HEMI V8 engine, this set of eight pistons offers a perfect balance of durability and precision for heavy to severe duty race applications.

Whether you are building a track-only race engine or a high-output street performance build, these pistons provide the foundation needed to handle increased cylinder pressures and aggressive tuning. With premium piston rings included, you’ll get enhanced sealing and long-lasting performance under extreme conditions.

Key Features:

Wiseco’s Professional Series pistons incorporate advanced design and manufacturing techniques to deliver superior performance and durability:

• Forged from high-strength aluminum alloy for exceptional toughness and heat resistance.
• 5.5cc dome design to optimize combustion chamber volume and support higher compression ratios.
• 1.220 inch compression height engineered for precise fitment in the 6.1L HEMI block.
• 0.984 inch wrist pin diameter for robust pin connection and reduced wear.
• Set of 8 pistons matched for consistent performance across all cylinders.
• Includes premium piston rings for improved sealing and reduced blow-by.
• Designed to withstand the rigors of heavy-duty racing and high-boost forced induction setups.
• Precision machining ensures optimal balance and reduced reciprocating mass.

Construction & Design:

Each piston in this Professional Series set is forged using Wiseco’s proprietary forging process, which enhances the metal grain structure for increased strength and fatigue resistance. The dome shape is carefully engineered to complement the 6.1L HEMI’s combustion chamber, promoting efficient flame propagation and power output.

The pistons feature a durable skirt coating to minimize friction and wear, extending engine life even under severe operating conditions. The compression height and wrist pin dimensions are optimized for a direct replacement fit, ensuring seamless installation without modification.

Installation & Fitment:

This piston set is designed as a direct fit for Chrysler 6.1L 3rd Gen HEMI engines with a 4.060 inch bore. Installation requires standard engine assembly procedures and proper ring end gap setting. No special modifications to the block or connecting rods are necessary when using these pistons.

• Direct replacement for factory pistons in 6.1L HEMI engines.
• Compatible with heavy-duty race builds and high-performance street engines.
• No cutting, drilling, or special tuning required for fitment.
