What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these Wiseco pistons is designed to reduce operating friction and noise. It also helps to minimize wear on both the piston skirt and the cylinder wall, contributing to a longer service life.

Are these pistons suitable for naturally aspirated engines, or only forced induction?

While these pistons are engineered for the strength and durability needed in performance racing and power adder applications, their robust construction from 2618 aluminum and optimized design also make them a strong choice for high-performance naturally aspirated builds.

What does the accumulator groove do?

The accumulator groove is incorporated into the piston design to help maintain consistent ring seal under demanding operating conditions. This helps to ensure optimal combustion efficiency and power output.

Product Details

If you're building a high-performance Chevrolet LS engine for drag racing or circle track, you need pistons that can handle serious abuse. Wiseco's RED series forged pistons are built for just that. They're forged and machined in the USA from 2618 aluminum, giving them the tensile strength required for demanding racing conditions and boosted applications.

These pistons feature a -4cc flat top design and a 1.294-inch compression height, with a 4.030-inch bore. Wiseco engineers these pistons with dedicated forgings for an optimized strutted design, balancing strength with a low weight. To further improve performance and longevity, they include horizontal slot oiling in the pin bores for consistent wrist pin lubrication and an ArmorGlide skirt coating that reduces friction, noise, and wear. Each set comes complete with premium rings, so you won't need to source them separately. An accumulator groove is also included to help maintain consistent ring seal and power output.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for serious performance builds where durability and precision are paramount.
