Wiseco Chevy LS Series -20cc R/Dome 4.135in Bore Piston Shelf Stock Kit

If you're building a high-performance Chevrolet LS engine for serious racing or heavy-duty use, this Wiseco Professional Series piston kit is a solid choice. These pistons are designed to handle the demands of severe duty applications, offering a combination of strength and advanced features that serious builders look for. The kit includes eight pistons, each with a -20cc dish volume, a 4.135-inch bore size, and a 1.110-inch compression height, along with a 0.927-inch pin diameter.

Wiseco crafts these pistons from 2618 aluminum, a material known for its improved tensile strength, making them well-built for the stresses of racing. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The piston crowns are fully machined for accuracy, and they incorporate forced pin oiling to ensure the wrist pins stay well-lubricated under extreme conditions. Additionally, the pistons come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly.

This kit is intended for builders who are pushing their LS engines to the limit. 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 manufacturer instructions for proper installation.
