Wiseco Chevy LS Series -3cc Dome 3.903inch Bore Piston Shelf Stock Kit

Starting with a -3cc dome volume and a 3.903-inch bore, this Wiseco piston set is built for serious LS engine builds. These aren't your average pistons; they're forged from 2618 aluminum right here in the USA, giving them improved tensile strength for the demands of heavy or severe duty racing applications. The precision machining extends to the ring grooves, which include anti-detonation features and additional sealing enhancements to keep combustion gases in check and power where it belongs.

Wiseco also applies their ArmorGlide skirt coating to these pistons. This isn't just for looks; it helps resist seizure, reduces friction for smoother operation, and contributes to quieter running, especially during break-in or at lower RPMs. The crown is fully machined, and the design incorporates forced pin oiling to ensure the wrist pins stay well-lubricated under high stress. This set includes eight pistons, designed to be a direct fit for your LS engine.

When you're building an engine that needs to handle extreme conditions, components like these pistons are crucial. They are designed to work with premium rings, which are included in the kit, to maximize performance and durability. Remember that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
