Wiseco Chevy LS Series -3.2cc FT 3.903inch Bore Piston Shelf Stock

Wiseco is known for making well-built performance engine components, and these Professional Series pistons are a prime example. If you're building or rebuilding a Chevrolet LS engine for serious performance, these pistons are designed to handle the demands of heavy to severe duty applications. They are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for durability under stress.

These pistons feature a -3.2cc dish volume and a 3.903-inch bore size, with a 1.3045-inch compression height and a 0.927-inch pin diameter. You'll find 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 noise while resisting seizure. The fully machined crown and forced pin oiling are also notable features for performance builds.
