What material are these pistons made from?

These pistons are forged from 2618 aluminum, which offers improved tensile strength compared to other aluminum alloys. This makes them well-suited for high-performance and severe duty applications.

What is the ArmorGlide skirt coating for?

The ArmorGlide skirt coating is applied to help reduce friction between the piston skirt and cylinder wall. This also contributes to seizure resistance and quieter operation of the engine.

Are these pistons compatible with all LSX engines?

This set is specifically designed for LSX engines with a 4.070 inch bore and a 1.110 inch compression height. It's important to verify these specifications against your engine build requirements and consult manufacturer fitment data.

Product Details

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for serious racers and builders who need parts that can handle extreme conditions. These pistons are designed and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds.

You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, ensuring efficient combustion and durability. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown is ready for your build, and forced pin oiling helps keep things lubricated under heavy load. These are built to withstand heavy to severe duty performance applications, so you can push your engine hard.

This set includes eight pistons, each with a 4.070-inch bore and a 1.110-inch compression height. Remember, these are not CARB approved and cannot be shipped to California. Please check manufacturer fitment data to confirm compatibility with your specific vehicle and engine build.
