Wiseco Chevy Small Block 4.125in Bore 1.100in CH 10.00 CC Piston Set

In this set, you'll receive eight forged pistons designed for Chevrolet Small Block engines with a 4.125-inch bore. These are Wiseco's Professional Series pistons, built for serious racers and builders who need top-tier performance and durability in heavy to severe duty race applications. They are engineered, forged, and machined right here in the USA.

These pistons are crafted from 2618 aluminum, which offers improved tensile strength for demanding conditions. You'll find precision ring grooves, an anti-detonation groove, and other features designed to enhance ring seal. The piston crown is fully machined, and they include forced pin oiling to keep things lubricated. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation.

Because these are built for severe duty, they are a solid option if you're putting together a high-performance engine that will see intense use. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
