Wiseco Chevy LS Series -2.8cc Dome 4.135inch Bore Piston Kit

Starting with the 2618 aluminum construction, these Wiseco pistons are forged and machined in the USA. This material choice is key for improved tensile strength, which is crucial when you're pushing an engine hard. The -2.8cc dome design and 4.135-inch bore are specific to certain LS engine builds, aiming for a particular compression ratio and displacement.

Wiseco has packed these Professional Series pistons with features for serious builders. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The ArmorGlide skirt coating is a notable addition, helping to reduce friction and noise while also resisting seizure, which is a common concern in high-performance applications. The fully machined crown and forced pin oiling further contribute to their ability to handle heavy to severe duty performance demands.

This set includes eight pistons, designed for the Chevrolet LS engine platform. While these are built for demanding race applications, remember they are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in their LS engine, this Wiseco kit offers a well-built solution.
