Wiseco Chevy Small Block 4.155in Bore 1.062in CH 3.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series piston set is built for serious racers and builders who need parts that can handle extreme conditions. These pistons are designed for heavy to severe duty race builds, meaning they are constructed to withstand the intense demands of competition engines.

Each piston in this set is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength compared to other aluminum alloys. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The piston crown is fully machined for accuracy. For reduced friction and quieter operation, these pistons also come with an ArmorGlide skirt coating, which is resistant to seizure. The design also includes forced pin oiling to ensure the wrist pin stays well-lubricated under high stress.

This set includes eight pistons, each designed for a 4.155-inch bore with a 1.062-inch compression height and a 0.927-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. They are intended for off-road use or racing applications where emissions regulations may differ.
