Wiseco Chevy LS Pistons 3.900 Stroker w/ .927 Pin Kit - Set of 8

Starting with a 3.780 inch bore and a 1.165 inch compression height, this set of eight Wiseco Professional Series pistons is built for serious performance in Chevrolet LS engines. These aren't your average pistons; they're forged from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of heavy to severe duty racing applications. The machining process is precise, featuring anti-detonation grooves and additional features designed to improve ring seal, which is critical for maintaining compression and power under extreme conditions.

Wiseco has also applied their ArmorGlide skirt coating to these pistons. This isn't just for looks; it helps reduce friction between the piston skirt and cylinder wall, which can lead to quieter operation and improved durability by resisting seizure. The fully machined crown ensures a clean combustion chamber surface, and forced pin oiling helps keep the wrist pin lubricated, further enhancing longevity in high-stress builds. This set includes the necessary .927 inch pin kit to get these pistons installed.

If you're building a high-performance LS engine for racing or severe duty use, these Wiseco pistons are a solid option. Keep in mind 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.
