About this part

Product Details

If you're rebuilding a high-performance Chevrolet LT1 engine, this set of Wiseco Professional Series pistons is built to handle some serious work. These aren't your average pistons; they're forged from 2618 aluminum right here in the USA, giving them improved tensile strength for demanding applications. The 4.070-inch bore size is specific to certain LT1 builds, and the -6.90 CC dish helps achieve your desired compression ratio.

Wiseco has packed these pistons with features to ensure durability and performance under heavy loads. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are further details that show these pistons are made for severe duty and racing use.

This set includes eight pistons, along with premium rings, ready for your engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust LT1 build that needs to withstand significant stress, this Wiseco set is a solid choice.
