What material are these Wiseco pistons made from?

These Wiseco RED Series pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, making it suitable for demanding performance and racing applications.

What is the purpose of the ArmorGlide skirt coating?

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

Are these pistons compatible with all LS engines?

These pistons are specifically designed for Chevrolet LS engines with a 4.000 inch bore. It's important to verify your engine's specific bore size and compression height requirements to ensure proper fitment.

Product Details

When you're building a high-performance Chevrolet LS engine, whether for drag racing, circle track, or serious street use, the pistons are a critical component. Wiseco's RED Series forged pistons are built to handle the demands of racing and power adder applications, offering a strong foundation for your build.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its tensile strength needed in high-stress environments. Wiseco engineers these pistons with dedicated forgings for LS engines, creating an optimized strutted design that maximizes strength while keeping weight down. The horizontal slot oiling in the pin bores is a notable detail that ensures proper wrist pin and small-end lubrication, which is key for long service life under demanding conditions. Additionally, the ArmorGlide skirt coating helps reduce friction and noise, contributing to less wear on the piston skirts and cylinder walls.

This set includes premium rings, so you won't need to source those separately. An accumulator groove is also incorporated to help maintain consistent ring seal and power output. Please note that these pistons are not CARB approved and cannot be shipped to California.
