Wiseco Chevy Big Block 4.615in Bore 1.065in CH 15.60 CC Piston Set

Wiseco is well-known for making strong, reliable engine components, especially for high-performance applications. This Professional Series piston set is built for serious racers and builders who need top-tier performance and durability in their Chevy Big Block engines. These aren't your average pistons; they're designed from the ground up to handle the demands of heavy to severe duty race builds, pushing the limits of what your engine can do.

Each piston is forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for those high-stress situations. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, ensuring efficient combustion. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their robust design, making them ready for intense competition.

This set includes eight pistons, each designed for a 4.615-inch bore with a 1.065-inch compression height and a 0.990-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a serious race engine and need pistons that can withstand extreme conditions, this Wiseco set is a solid option.
