Wiseco Chevy LSX Junkyard Dog 5.3L .945in Pin 3.780 Bore NA/Boost/Nitrous Drop In Replacement Piston

This set includes eight Wiseco Professional Series pistons, designed for Chevrolet LS 5.3L engines. These pistons are a drop-in replacement, meaning they are built to fit your existing setup with minimal modification, making them suitable for naturally aspirated, boosted, or nitrous applications. They feature a 3.780-inch bore and utilize a .945-inch pin diameter.

Crafted in the USA from 2618 aluminum, these pistons are forged and machined for improved tensile strength, which is crucial for handling the stresses of high-performance engines. The design includes precision ring grooves, anti-detonation grooves, and features aimed at improving ring seal. Additionally, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their durability and performance under heavy to severe duty conditions.

These pistons are intended for serious racers and builders who demand robust components for their engine builds. Please note that this product is not CARB approved and cannot be shipped to California.
