Product Details

If you're rebuilding the heart of your Chevrolet LT1 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 right here in the USA from 2618 aluminum, a material known for its improved tensile strength, making these pistons well-suited for high-stress environments.

Wiseco has packed these pistons with features aimed at improving performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features designed to enhance ring seal. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pin properly lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and longer life under demanding conditions. This set includes eight pistons, ready to be installed in your LT1 block.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, ensure you have all the necessary supporting components and refer to the manufacturer's installation instructions for proper fitment and assembly.
