Key Features
Wiseco’s Professional Series pistons combine advanced engineering and manufacturing techniques to meet the demands of high-stress, high-heat environments. Key features include:
- Forged aluminum construction for maximum strength and resistance to fatigue and thermal stress
- 4.090 inch bore size, perfectly matched to the Chrysler 6.4L Gen III HEMI specifications
- 1.210 inch compression height optimized for ideal engine geometry and performance
- 9.50cc dome volume designed to support custom compression ratios and efficient combustion
- 0.927 inch wrist pin diameter for enhanced pin strength and durability under high loads
- Professional Series design tailored for severe duty racing and high-output street engines
- Premium piston rings included for superior sealing and reduced friction
- Precision machining ensures consistent fitment and balance across all eight pistons
- Compatible with factory and aftermarket rods and components designed for the 6.4L Gen III HEMI
Construction & Design
Each piston is forged from a high-quality aluminum alloy, providing an ideal balance of lightweight strength and excellent thermal conductivity. The forging process refines the grain structure, significantly improving fatigue resistance compared to traditional cast pistons. The dome shape and volume are engineered to optimize combustion efficiency and power delivery specific to the Gen III HEMI platform.
Wiseco’s meticulous machining and finishing processes ensure tight tolerances and smooth surface finishes, which reduce internal friction and enhance ring sealing. This attention to detail guarantees reliable performance and longevity, even under the most demanding racing or high-performance conditions.
Installation & Fitment

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
