Wiseco RED Series Chevy Big Block 4.280in Bore 1.270in CH 15.00 CC Piston Set

If you're building a high-performance Chevy Big Block engine for serious racing, the Wiseco RED Series pistons are designed to handle the demands. These aren't your average pistons; they're built with Race Engineered Design (RED) principles to give you a strong foundation for power and durability. They are forged and machined right here in the USA from 2618 aluminum, a material known for its tensile strength, which is crucial when you're pushing an engine hard, whether that's on the drag strip or the circle track.

Wiseco has included some thoughtful features to ensure these pistons perform and last. The horizontal slot oiling in the pin bores is a smart touch that keeps the wrist pin and the small end of the connecting rod well-lubricated, which is vital for preventing premature wear. The dedicated forgings allow Wiseco to optimize the strutted design for each specific engine, maximizing strength while keeping weight down. You'll also find an ArmorGlide skirt coating, which helps reduce friction and noise, leading to less wear on both the piston skirt and the cylinder wall. Plus, each set comes with premium rings, so you don't have to hunt for compatible ones separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

This set is for an 8-cylinder engine and is specifically designed for a 4.280-inch bore. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are a solid option for anyone serious about building a powerful and reliable performance engine.
