Wiseco Chevy Small Block 4.060in Bore 1.250in CH 13.50 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is built for Chevy Small Block engines and is designed for serious racers and builders who need parts that can handle heavy to severe duty use. If you're rebuilding a high-performance engine and want pistons that are built to last under extreme conditions, these are a solid option.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is also fully machined. For reduced friction and quieter operation, they come with an ArmorGlide skirt coating, which also helps prevent seizures. The design includes forced pin oiling to keep the wrist pins well-lubricated.

This set includes eight pistons, each with a 4.060-inch bore and a 1.250-inch compression height. The wrist pin diameter is 0.927 inches, and the dish volume is 13.50 CC. Please note that these pistons are not CARB approved and cannot be shipped to California.
