Wiseco Chevy Big Block 4.310in Bore 1.270in CH 25.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds. The 4.310-inch bore size is specific to Chevy Big Block engines, and the 1.270-inch compression height, combined with a 25.00 CC dish volume, is crucial for achieving your desired compression ratio when paired with your specific cylinder heads and crankshaft.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure reliable performance under extreme conditions. The crown is fully machined for accuracy, and forced pin oiling helps keep the wrist pin lubricated. For added durability and reduced friction, these pistons come with an ArmorGlide skirt coating, which helps prevent seizure and quiets operation.

This set includes eight pistons, designed to withstand severe duty applications. While these pistons are built for maximum performance, please note they are not CARB approved and cannot be shipped to California. If you're building a high-performance or race engine, these Wiseco pistons offer a well-built foundation.
