Wiseco RED Series Chevrolet Big Block 4.600in Bore 1.155in CH 15.00 CC Piston Set

If you're building a serious performance Chevrolet Big Block engine, you need pistons that can handle the stress. This set from Wiseco's RED Series is designed for just that. They're forged from 2618 aluminum, a material known for its high tensile strength, making these pistons well-suited for racing and applications with power adders like turbochargers or superchargers.

Wiseco's Race Engineered Design (RED) philosophy means these pistons aren't just strong; they're smart. They feature horizontal slot oiling in the pin bores to ensure the wrist pins and connecting rod small ends stay properly lubricated, which is crucial for longevity. The dedicated forgings allow for an optimized, engine-specific strutted design that balances strength with weight, helping your engine rev more freely. Plus, the ArmorGlide skirt coating is applied to reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls. You also get accumulator grooves to help maintain consistent ring seal and power delivery.

This set includes premium rings, so you won't need to source them separately. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for a 4.600-inch bore with a 1.155-inch compression height and a 0.990-inch pin diameter.
