Wiseco Chevy LS 4.085in Bore 1.165in CH -9.00 CC Piston Set

If you're building a high-performance Chevy LS engine for serious racing or heavy-duty applications, this set of Wiseco Professional Series pistons is a solid choice. These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for handling the extreme pressures found in race engines. They feature a 4.085-inch bore and a 1.165-inch compression height, with a -9.00cc dish that helps achieve a specific compression ratio tailored for performance builds.

Wiseco has packed these pistons with features aimed at durability and performance. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, ensuring efficient combustion and preventing blow-by. The piston crowns are fully machined for accuracy, and they come with forced pin oiling to keep the wrist pins properly lubricated under high stress. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, even in severe duty conditions. This set includes eight pistons, ready for your next demanding build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders working on extreme performance LS engines, these Wiseco pistons are designed to handle the rigors of competition and severe duty use.
