Wiseco RED Series Chevy LS 4.015in Bore 1.294in CH -15.00 CC Piston Set

When you're rebuilding the top end of a high-performance Chevy LS engine, especially for demanding applications like drag racing or circle track, the pistons are a critical component. The Wiseco RED Series pistons are built to handle the stress and heat that come with serious performance builds. They utilize Race Engineered Design (RED) principles to give you the strength you need without unnecessary weight.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is essential for racing and engines with power adders. Wiseco has incorporated features like horizontal slot oiling in the pin bores to ensure the wrist pin and small end of the connecting rod stay well-lubricated, contributing to a longer service life. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. Additionally, the ArmorGlide skirt coating is applied to reduce friction and noise, and it also helps minimize wear on the piston skirt and cylinder wall. Each set comes complete with premium rings, so you won't need to source those separately.

An accumulator groove is also included to help maintain consistent ring seal and power output. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're looking for a well-built, performance-oriented piston set for your LS engine, this Wiseco RED Series set is a solid option.
