Wiseco Chevy LS 3.905in 1.165in CH -17.00 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 demand the best for their Chevy LS engine. These aren't just pistons; they're a key part of a robust engine build designed to handle heavy to severe duty performance. If you're pushing your LS engine hard, these pistons are made to keep up.

Crafted from 2618 aluminum right here in the USA, these pistons are forged and machined for improved tensile strength. You'll find precision ring grooves, an anti-detonation groove, and other features that help improve ring seal, which is crucial for consistent power and engine longevity. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown is ready for your build, and forced pin oiling ensures the wrist pins stay well-lubricated under extreme conditions.

This set includes eight pistons, each with a 3.905-inch bore and a 1.165-inch compression height. The wrist pin diameter is 0.927 inches. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in their LS engine, this Wiseco set is a solid choice.
