Wiseco Chevrolet LT1 4.070in Bore 1.304in CH -12.00 CC Professional Piston Set

Forged from 2618 aluminum, these Wiseco Professional Series pistons are built for the demands of severe duty racing applications. The 4.070-inch bore size is specific to certain Chevrolet LT1 engine builds, and the 1.304-inch compression height, combined with a -12.00cc dish volume, is crucial for achieving the correct compression ratio with your chosen cylinder heads and camshaft.

Wiseco machines these pistons in the USA, ensuring precision in every detail. You'll find accurately cut ring grooves designed for optimal seal, along with anti-detonation grooves to help prevent detonation damage. The crown is fully machined for a clean, consistent combustion chamber shape. Additionally, these pistons feature forced pin oiling to ensure the wrist pin receives adequate lubrication under high stress, and they come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and operate more quietly, all important factors when pushing an engine to its limits.

This set includes eight pistons, the wrist pins, and premium rings, ready for installation in your high-performance Chevrolet LT1 engine. Please note that these pistons are not CARB approved and cannot be shipped to California.
