What material are these pistons made from?

These Wiseco pistons are forged from 2618 aluminum, which is known for its improved tensile strength. This material is chosen for its ability to withstand the high pressures and temperatures found in severe duty race engines.

What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these pistons is designed to reduce friction between the piston skirt and the cylinder wall. This also helps to resist seizure and contributes to quieter operation of the engine.

Are these pistons suitable for a street-driven vehicle?

These are Professional Series pistons designed for heavy to severe duty race builds. While they are well-built, they are not CARB approved and are intended for high-performance applications where maximum durability under extreme conditions is required.

Product Details

If you're building a serious performance engine for your Chrysler 6.1L Hemi, Wiseco's Professional Series forged pistons are a solid choice. This set of eight pistons is designed for heavy to severe duty race applications, meaning they're built to handle the extreme demands of high-performance engines. They feature a 5.5cc dome and a 1.220 inch compression height, with a 4.055 inch bore to match your 6.1L Hemi.

These pistons are forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for durability under pressure. Wiseco has included precision ring grooves, anti-detonation grooves, and other features to enhance ring seal and prevent detonation. The crown is fully machined for a clean finish, and the pistons also benefit from forced pin oiling to keep the wrist pins properly lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly.

This set is intended for dedicated racers and builders who need a well-built component for their custom engine builds. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, always refer to the manufacturer's installation instructions and recommended assembly procedures.
