What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these Wiseco pistons is designed to reduce friction between the piston and cylinder wall. This helps prevent seizure and contributes to quieter operation, especially under high-performance conditions.

What is the compression height and pin diameter?

These pistons have a compression height of 1.220 inches and a pin diameter of 0.945 inches. These measurements are critical for proper engine assembly and achieving the correct compression ratio.

Are these pistons suitable for a street-driven vehicle?

Wiseco's Professional Series pistons are designed and built for heavy to severe duty race applications. While they can be used in high-performance street builds, they are optimized for demanding conditions and may require additional supporting modifications for optimal street use.

Product Details

If you're building a serious performance engine for your Chrysler 5.7L HEMI, Wiseco's Professional Series forged pistons are a solid choice. These aren't your average pistons; they're crafted from 2618 aluminum, which offers improved tensile strength over other alloys, making them well-suited for the demands of heavy to severe duty racing builds. The set includes eight pistons, each with a 3.937-inch bore and a +6.55cc dome to help achieve your desired compression ratio.

Wiseco puts a lot of thought into the details that matter for high-performance engines. You'll find precision ring grooves, anti-detonation grooves, and features designed for better ring seal, all contributing to improved engine efficiency and durability under stress. The piston crowns are fully machined, and they come with forced pin oiling to ensure proper lubrication. Plus, these pistons feature an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit when pushing an engine hard.

When you're aiming for maximum performance and reliability in a race application, Wiseco's Professional Series pistons are designed to handle the pressure. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have all the necessary supporting components and follow the manufacturer's installation guidelines.
