Wiseco Chevrolet LS 4.070in Bore 3.900in Stroke 1.165CH -9cc Dish - Set of 8

If you're building a high-performance Chevrolet LS engine for serious racing, these Wiseco Professional Series forged pistons are a solid choice. They are designed to handle the demands of heavy to severe duty applications, giving you the confidence to push your engine to its limits. With a 4.070-inch bore and a 3.900-inch stroke, these pistons are crafted from 2618 aluminum, a material chosen for its improved tensile strength, making them well-built for racing environments.

Wiseco has packed these pistons with features aimed at enhancing both performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown is fully machined for accuracy, and they include forced pin oiling to keep the wrist pins lubricated under high stress. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit in high-RPM applications. This set includes eight pistons, complete with premium rings, ready for your custom build.

Remember that these pistons are not CARB approved and cannot be shipped to California. Ensure you check all manufacturer specifications and installation guidelines before beginning your build.
