Wiseco RED Series Chevy LS 4.135in Bore 1.105in CH -20.00 CC Piston Set

If you're building a high-performance Chevy LS engine, Wiseco's RED Series pistons are a solid choice. These aren't your average pistons; they're forged from 2618 aluminum, a material known for its tensile strength, making them well-suited for demanding racing applications and engines with power adders like turbochargers or superchargers. The Race Engineered Design (RED) process means these pistons are specifically optimized for strength and durability while keeping weight in check, which is crucial for engine longevity and performance.

Wiseco has thought through the details here. You'll find horizontal oiling slots in the pin bores, which help keep the wrist pin and connecting rod small end properly lubricated, a critical factor for preventing wear. Each set also comes with premium rings, so you won't have to hunt for compatible ones separately. The accumulator groove is another smart touch, designed to help maintain consistent ring seal, which translates directly to better compression and more power. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also cutting down on skirt and cylinder wear, contributing to a longer service life for your build.

This set is designed for a 4.135-inch bore with a 1.105-inch compression height and a -20.00cc dish volume. Remember, these pistons are not CARB approved and cannot be shipped to California. They are manufactured in the USA, reflecting a commitment to quality and domestic production.
