Wiseco Chevy Small Block 4.040in Bore 1.550in CH -15.00 CC Piston Set

If you're rebuilding the heart of your Chevrolet Small Block engine for serious racing or heavy-duty performance, a strong set of pistons is crucial. This Wiseco Professional Series piston set is built from the ground up to handle the demands of severe duty applications. Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is essential for high-stress engine builds.

These pistons feature an ArmorGlide skirt coating that helps reduce friction and resist seizure, while also contributing to quieter operation. The fully machined crown includes precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, ensuring efficient combustion and power delivery. The forced pin oiling system is also a key feature for maintaining lubrication in demanding conditions. Wiseco designed this set to be a solid option for builders who need reliable performance under extreme loads.

This set includes eight pistons, designed for a 4.040-inch bore with a 1.550-inch compression height and a -15.00 CC dish. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
