Wiseco Chevrolet LSX 6.0 4.000in Bore 9.7cc Dome 0.945 Pin Dia Piston Kit

This Wiseco piston kit includes a set of eight pistons, designed for Chevrolet LSX 6.0L engines with a 4.000-inch bore. These are Wiseco's Professional Series pistons, built for serious racing and heavy-duty applications where durability and performance are critical. They are engineered and forged in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is essential for handling the high stresses of performance engines.

Each piston features a 9.7cc dome and a 0.945-inch pin diameter. The precision ring grooves, anti-detonation grooves, and other ring seal improvements are designed to ensure optimal compression and combustion efficiency. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown and forced pin oiling further enhance their ability to withstand severe duty performance demands.

These pistons are intended for builders who are pushing their engines to the limit. While they offer significant performance and durability advantages, please note that they are not CARB approved and cannot be shipped to California. For a complete build, consider pairing these with appropriate connecting rods and other internal engine components.
