Wiseco Chevy Small Block 4.060in Bore 1.250in CH -5.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is built for serious racers and builders who need parts that can handle heavy to severe duty use. They are designed and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds.

These pistons feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction and resist seizure, while also making operation quieter. The fully machined crown and forced pin oiling are details that show these are built for performance and durability under tough conditions. This set is for a 4.060 inch bore with a 1.250 inch compression height and a -5.00cc dish volume.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding a high-performance Chevy Small Block engine, these pistons are a solid option for ensuring the internals can withstand the stress of racing or severe duty.
