Wiseco Chevrolet LS 4.070in Bore 1.110in CH -15.00 CC Professional Piston Set

Wiseco is known for making well-built performance engine components, and their Professional Series pistons are a prime example of that dedication. If you're building a serious LS engine for your 1997-2004 Chevrolet Corvette, these pistons are designed to handle the demands of heavy to severe duty racing applications. They are engineered, forged, and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to withstand the stresses of high-performance use.

These aren't just basic pistons; they come packed with features aimed at maximizing performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The crown is fully machined for accuracy, and they even include forced pin oiling to keep things well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, making for a smoother, more reliable operation under extreme conditions.

This set includes eight pistons, each with a 4.070-inch bore and a 1.110-inch compression height, and they use a 0.927-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders looking to push the limits of their LS engine, these Professional Series pistons offer a solid foundation.
