Wiseco Chevy Small Block 4.130in Bore 1.120in CH 3.00 CC Piston Set

If you're rebuilding a high-performance Chevy Small Block engine for serious racing or heavy-duty use, a strong set of pistons is crucial. This Wiseco Professional Series piston set is built to handle the demands of severe duty applications, offering a significant upgrade over stock components. They are designed to work with a 4.130-inch bore and feature a 1.120-inch compression height, making them suitable for many popular small block builds.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress. Wiseco has incorporated several features to enhance performance and durability, including precision ring grooves, an anti-detonation groove, and additional features for improved ring seal. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated. For reduced friction, quieter operation, and improved seizure resistance, these pistons also come with an ArmorGlide skirt coating.

This set includes eight pistons, designed for 8-cylinder engines. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
