Wiseco SBC LS7 +2.5cc Dome 1.175inch CH Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable engine components for performance applications. This Professional Series piston kit is built for the serious racer or builder who needs parts that can handle heavy to severe duty use. These pistons are designed to remove limits in your engine build, offering custom-level performance and durability features right out of the box.

Each piston in this set is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding conditions. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown is fully machined, and they include forced pin oiling to ensure proper lubrication. For reduced friction and quieter operation, the skirt is coated with ArmorGlide, which also helps prevent seizure.

This kit includes 8 pistons, each with a +2.5cc dome volume and a 1.175-inch compression height, designed for a 4.125-inch bore. The pin diameter is 0.9252 inches. Please note that these pistons are not CARB approved and cannot be shipped to California.
