Wiseco Chevy LS 4.035in Bore 1.250in CH -13.00 CC Piston Set

If you're rebuilding the heart of your Chevy LS engine for serious racing or heavy-duty performance, a strong set of pistons is where you start. This Wiseco Professional Series piston set is built from the ground up to handle the extreme demands of competition and severe duty applications. They are designed to be a core component in high-performance LS builds where reliability under stress is paramount.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for handling the high pressures and temperatures found in racing engines. Wiseco has incorporated several features to enhance performance and durability, including precision ring grooves, anti-detonation grooves, and other ring seal improvements. The crown of each piston is fully machined for accuracy, and they feature forced pin oiling to ensure the wrist pins stay well-lubricated. Additionally, the skirt coating, known as ArmorGlide, helps reduce friction, resist seizure, and operate more quietly, contributing to overall engine efficiency and longevity.

This set includes eight pistons, each with a 4.035-inch bore, a 1.250-inch compression height, and a -13.00 CC dish volume, making them suitable for specific compression ratio targets in performance LS engines. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
