Wiseco Chevy Big Block 4.605in Bore 1.155in CH 15.60 CC Piston Set

What you get in this box is a set of eight Wiseco Professional Series forged pistons, ready to go into your Chevy Big Block engine. These aren't your average pistons; they're built from 2618 aluminum, forged and machined right here in the USA, giving them improved tensile strength for demanding builds. The bore size is 4.605 inches, with a compression height of 1.155 inches and a pin diameter of 0.990 inches. The piston crown is fully machined, and they feature precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal.

Wiseco has added an ArmorGlide skirt coating to these pistons. This coating helps resist seizure, reduces friction, and makes for quieter operation, which is a big deal when you're pushing an engine hard. These pistons are designed and built to handle heavy to severe duty performance applications, meaning they're made for serious racing and high-stress builds. They also feature forced pin oiling to ensure the wrist pins stay well-lubricated under extreme conditions.

Keep in mind that these pistons are not CARB approved, so they cannot be shipped to California. If you're building a high-performance Chevy Big Block for racing or severe duty use, this set is a solid option to consider for its robust construction and performance-oriented features.
