What material are these pistons made from?

These pistons are forged from 2618 aluminum. This material is chosen for its improved tensile strength, making the pistons well-suited for high-performance and severe duty applications.

What is the ArmorGlide skirt coating for?

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

Are these pistons compatible with all LS engines?

These pistons are specifically designed for Chevy LS engines with a 3.905-inch bore and a 1.165-inch compression height. It's important to verify these dimensions match your specific engine build requirements.

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 Chevy LS engines with a 3.905-inch bore. These aren't your average pistons; they're designed for serious racers and builders who push their engines hard, handling heavy to severe duty performance builds.

Each piston is forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to handle the intense pressures of racing. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and makes for quieter operation. The fully machined crown and forced pin oiling further contribute to their durability and performance under extreme conditions.

This set includes eight pistons, ready to be installed in your LS engine. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance LS engine that needs to withstand serious abuse, these Wiseco pistons are a solid choice.
