Wiseco RED Series Chevy Big Block 4.280in Bore 1.395in CH 21.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components for performance applications. This RED Series piston set is built for Chevy Big Block engines and is designed to handle the demands of racing and high-power builds. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard, whether on the drag strip or the circle track.

The Race Engineered Design (RED) means these pistons have features specifically machined to give you an edge. For instance, the horizontal slot oiling in the pin bores ensures the wrist pin and connecting rod small end stay well-lubricated, which is key for long-term durability. Wiseco also uses dedicated forgings for each engine application, allowing them to create an optimized strutted design that maximizes strength while keeping weight down. To further reduce friction and wear, these pistons come with an ArmorGlide skirt coating, which also helps quiet down operation. You'll also find an accumulator groove, designed to help maintain consistent ring seal and power delivery.

This set includes premium rings, so you won't need to source those separately. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are manufactured in the USA.
