What makes the RED Series pistons different?

The RED (Race Engineered Design) series uses dedicated forgings to create a strutted design that maximizes strength-to-weight ratio. They are forged and machined in the USA from 2618 aluminum for high tensile strength needed in performance racing and power adder applications.

What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these pistons helps to reduce operating friction and noise. It also contributes to reducing skirt and cylinder wear, promoting longer service life for your engine components.

Are these pistons compatible with all LS engines?

These pistons are specifically designed for Chevrolet LS engines with a 4.155 inch bore. It's important to verify this bore size matches your specific engine build before purchasing.

Product Details

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of high-performance Chevrolet LS engines. The RED (Race Engineered Design) series uses dedicated forgings to create a strutted design that maximizes strength while keeping weight down, making them a solid choice for drag racing, circle track, or any application where you're pushing serious power. The 4.155-inch bore size is specific to certain LS engine builds, so make sure this matches your project's requirements.

You'll find features here that really matter for longevity and performance. The horizontal slot oiling in the pin bores ensures your wrist pins and connecting rod small ends stay well-lubricated, which is crucial for preventing wear under high stress. Plus, each set comes with premium rings, so you don't have to hunt for compatible ones. The accumulator groove is a smart touch, helping to maintain consistent ring seal and keep power delivery smooth and reliable.

Wiseco also includes an ArmorGlide skirt coating on these pistons. This isn't just for looks; it actively reduces friction and noise during operation, and it helps cut down on skirt and cylinder wear. These pistons are machined in the USA, reflecting a commitment to quality construction for serious engine builds. Keep in mind these are not CARB approved and cannot be shipped to California.
