What material are these Wiseco pistons made from?

These pistons are forged and machined in the USA from 2618 aluminum. This material is chosen for its high tensile strength, which is necessary for performance racing and power adder applications.

What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these pistons is designed to reduce operating friction and noise. It also helps to minimize wear on the piston skirts and the cylinder walls.

Are these pistons compatible with all Chevrolet LS engines?

This piston set is specifically designed for Chevrolet LS engines with a 4.020 inch bore and a -4cc dish. It is important to verify that these specifications match your engine build before installation.

Product Details

Wiseco is well-known for making strong, reliable forged pistons for performance applications. This RED? series piston kit is built for Chevrolet LS engines, offering the kind of strength and durability that serious racing and performance builds demand. These aren't just generic pistons; they're precision-machined using Race Engineered Design? to give you a real competitive edge, whether you're on the drag strip or the circle track.

These pistons are forged and machined right here in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard or adding power adders. They feature horizontal slot oiling in the pin bores to keep the wrist pins and the small end of the connecting rods well-lubricated, helping to ensure a long service life. The dedicated forgings allow for an engine-specific strutted design, which maximizes strength while keeping the weight down. Plus, the ArmorGlide? skirt coating is there to reduce friction and noise, and it also helps cut down on skirt and cylinder wear.

This set comes complete with premium rings, so you won't have to hunt for those separately. There's also an accumulator groove included, which helps maintain consistent ring seal and power delivery. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
