Wiseco Chevy LT1 4.065in Bore 1.299in CH -2.00 CC Piston Set

If you're building a high-performance Chevrolet LT1 engine for serious racing or severe duty applications, a strong set of pistons is fundamental. This Wiseco Professional Series piston set is designed to handle the extreme demands of competition, offering a robust foundation for your build. Each piston is forged from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for withstanding the high pressures and temperatures found in racing engines.

Wiseco has packed these pistons with features aimed at maximizing performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, ensuring efficient combustion and preventing blow-by. The fully machined crown ensures precise volume, and the forced pin oiling helps keep the wrist pin lubricated under extreme conditions. Additionally, the ArmorGlide skirt coating reduces friction and noise while also providing resistance to seizure, helping your engine run smoother and last longer under stress.

This set includes eight pistons, each with a 4.065-inch bore, a 1.299-inch compression height, and a -2.00cc dish volume. The wrist pin diameter is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California. They are built for heavy to severe duty race builds, so they represent a significant upgrade for any performance-oriented LT1 engine.
