About this part

Product Details

If you're building a high-performance Chevrolet LS engine for serious racing or heavy-duty applications, Wiseco's Professional Series forged pistons are a solid choice. These aren't your average pistons; they're crafted from 2618 aluminum, which offers improved tensile strength over other alloys, making them well-suited for the intense demands of racing. The set includes eight pistons, each designed to handle the stress of severe duty builds.

Wiseco puts a lot of thought into the details that matter for durability and performance. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is crucial for compression and preventing blow-by. The piston crown is fully machined for accuracy, and they feature forced pin oiling to keep the wrist pins lubricated under extreme conditions. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and longer life even when pushed hard.

Because these are built for racing, they are not CARB approved and cannot be shipped to California. This set is designed to be a direct replacement for your stock LS pistons, assuming your block has been machined to the 4.005-inch bore size. You'll want to ensure you have the correct supporting components, like rings and connecting rods, to match these high-performance pistons for your build.
