Wiseco Chevy LS 4.035in Bore 1.311in CH -9.70 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is a prime example, designed for serious racers and builders who need parts that can handle extreme conditions. These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds.

You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is critical for getting the most power and reliability out of your engine. They also come with an ArmorGlide skirt coating that helps resist seizure, reduces friction, and makes for quieter operation. The fully machined crown and forced pin oiling are details that show these are built to withstand heavy to severe duty performance applications. This set includes 8 pistons, each designed for a 4.035-inch bore with a 1.311-inch compression height and a -9.70cc dish volume.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance LS engine for racing or severe duty use, this set offers a solid foundation.
