Wiseco Chevy XLS FT 1.250inch CH (6413LX4RX4) Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston kit is built for serious racers and builders who need parts that can handle heavy to severe duty use. These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds.

You'll find a lot of attention to detail in these pistons. The fully machined crown features precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction, makes operation quieter, and resists seizure. Plus, the forced pin oiling system ensures the pins stay well-lubricated under stress. This kit is designed to withstand the rigors of intense racing and performance applications.

This set includes eight pistons, each with a 4.040-inch bore and a 1.250-inch compression height, and a 0.927-inch pin diameter. They fit a wide range of Chevrolet Small Block engines, including models like the Chevrolet Camaro, C10 Pickup, and Blazer. Please note that these pistons are not CARB approved and cannot be shipped to California.
