Wiseco Chevy LS 4.065in Bore 1.304in CH -3.2 CC 0.927in Pin Piston Shelf Stock Kit - Set of 8

If you're rebuilding the heart of your Chevy LS engine for serious racing or heavy-duty performance, Wiseco's Professional Series pistons are a solid choice. These aren't your average pistons; they're built from the ground up with custom-level features to handle the intense demands of severe duty applications. Wiseco forges and machines these pistons right here in the USA from 2618 aluminum, a material chosen for its improved tensile strength under extreme conditions.

You'll find precision in every detail, from the carefully machined ring grooves and anti-detonation features that ensure better ring seal, to the ArmorGlide skirt coating. This coating helps reduce friction and resist seizure, while also contributing to quieter operation. The fully machined crown and forced pin oiling further demonstrate the thought put into making these pistons reliable under pressure. This set includes eight pistons, ready to be installed in your LS engine.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, ensure you have all the necessary supporting components and refer to the manufacturer's installation instructions for proper fitment and assembly.
