Wiseco GM L83 Gen V -5cc Dome 3.800in Bore 10.5:1 CR Piston Kit - Set of 8

Wiseco is known for building tough, high-performance engine components, and their Professional Series forged pistons are a prime example of that commitment. If you're building a serious performance engine for your GM L83 Gen V, this set of eight pistons is designed to handle the demands of heavy to severe duty race applications. They are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for reliable performance under stress.

These aren't just basic pistons; they're packed with features to ensure optimal performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The piston crown is fully machined, and they include forced pin oiling to keep things well-lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit when you're pushing an engine hard.

This kit is designed to achieve a 10.5:1 compression ratio with a -5cc dome and a 3.800-inch bore. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a serious build, consider what else you might need, such as performance connecting rods and a full engine gasket set, to complete your project.
