What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide coating on the piston skirts is designed to reduce operating friction and noise. It also helps to minimize wear on both the piston skirts and the cylinder walls, contributing to longer engine life.

Are these pistons suitable for naturally aspirated engines as well as forced induction?

Yes, these RED series pistons are forged from 2618 aluminum and feature a design optimized for strength, making them suitable for both naturally aspirated performance builds and applications with power adders like turbochargers or superchargers.

What does the accumulator groove do?

The accumulator groove is designed to help maintain consistent ring seal and power delivery. It works in conjunction with the piston rings to ensure optimal combustion chamber sealing under high-performance conditions.

Product Details

Starting with a -4cc flat top dish and a 1.294-inch compression height, these Wiseco pistons are built for Chevrolet LS engines. They're forged from 2618 aluminum, a material chosen for the tensile strength performance racing and power adder applications demand. This set includes eight pistons, ready to be installed in your build.

Wiseco's RED series uses Race Engineered Design principles, meaning each piston is specifically shaped for its intended engine. This results in a strutted design that maximizes strength while keeping weight down. You'll also find horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pins and small ends of the connecting rods properly lubricated, extending their service life. The pistons also feature an accumulator groove, designed to help maintain consistent ring seal and power delivery under demanding conditions. Plus, the ArmorGlide skirt coating works to reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls.

This set comes complete with premium rings, so you won't need to source those separately. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For serious performance builds, these pistons offer a well-built foundation.
