Wiseco Chevy LT1 4.070in Bore 1.105in CH -20.00 CC Piston Set

This Wiseco Professional Series piston set includes eight forged pistons, designed for Chevrolet LT1 engines. Each piston features a 4.070-inch bore, a 1.105-inch compression height, and a -20.00cc dish volume, making them suitable for high-performance builds. These pistons are manufactured in the USA from 2618 aluminum, chosen for its improved tensile strength, and are fully machined for precise dimensions.

Wiseco has packed these pistons with features for serious racers and builders. You'll find precision ring grooves, anti-detonation grooves, and other features to improve ring seal. The ArmorGlide skirt coating helps reduce friction and resist seizure, while also contributing to quieter operation. Designed for heavy to severe duty performance applications, these pistons are built to handle demanding conditions. They also include forced pin oiling to ensure proper lubrication of the wrist pin.

Because these are intended for racing applications, they are not CARB approved and cannot be shipped to California. If you're rebuilding a high-performance LT1 engine for racing, this set offers a well-built foundation. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
