Wiseco Chevy LS 4.030in Bore 1.311in CH -9.70 CC Piston Set

If you're building a high-performance Chevrolet LS engine for serious racing or severe duty applications, this Wiseco Professional Series piston set is a solid choice. These pistons are specifically designed for a 4.030-inch bore size and feature a -9.70cc dish, which is crucial for setting your compression ratio. Wiseco builds these pistons in the USA from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of racing.

You'll find precision ring grooves on these pistons, along with features designed for additional ring seal, helping to ensure efficient combustion and prevent blow-by. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and contributes to quieter operation, which is a notable benefit when you're pushing an engine hard. The fully machined crown and forced pin oiling are also part of the package, all contributing to their ability to withstand heavy to severe duty performance use. This set includes eight pistons, ready for your next build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal results and longevity, always refer to the manufacturer's installation instructions and recommended assembly procedures.
