Wiseco Chevy LS Series 5cc Dome 1.110 x 3.903 Piston Shelf Stock Kit

If you're building a high-performance Chevrolet LS engine for serious racing or heavy-duty applications, this Wiseco Professional Series piston kit is a solid choice. These pistons are designed and built in the USA from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for the demands of severe duty performance builds. The 3.903-inch bore size and 5cc dome volume are specific to certain LS engine configurations, so be sure to confirm this is the correct size for your rebuild.

Wiseco has packed these pistons with features aimed at maximizing performance and durability. You'll find precision ring grooves, anti-detonation grooves, and additional features designed for improved ring seal. The fully machined crown ensures a consistent combustion chamber shape, while forced pin oiling helps keep the wrist pins lubricated under extreme conditions. They also come with an ArmorGlide skirt coating, which helps reduce friction and noise, and makes the pistons more resistant to seizure.

This kit includes a set of 8 pistons, along with premium rings, ready for installation. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
