Wiseco Chevy LS Series -25cc Dish 4.100inch Bore Piston Shelf Stock Kit

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance and durability in Chevy LS engines. The -25cc dish design is specifically chosen for certain compression ratio targets, and the 4.100-inch bore size is a common starting point for many LS engine builds. This kit is designed to handle the demands of heavy to severe duty racing applications, offering a well-built solution for builders looking to push their engines to the limit.

Wiseco engineers these pistons with features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure optimal combustion and longevity. The fully machined crown and forced pin oiling are further testament to their robust construction. An ArmorGlide skirt coating is applied to reduce friction, minimize wear, and operate more quietly, contributing to overall engine health under high stress. These pistons are forged and machined in the USA, reflecting a commitment to quality and performance.

This kit includes a set of eight pistons, ready for installation in a wide range of vehicles including models like the Cadillac CTS, Chevrolet Camaro, and Pontiac GTO. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
