Wiseco Chevrolet LS 4.005in Bore 1.304in CH -3.20 CC Professional Piston Set

If you're building a high-performance LS engine for your 1997-2004 Chevrolet Corvette, this Wiseco Professional Series piston set is built to handle serious power. These aren't your average pistons; they're forged from 2618 aluminum right here in the USA, giving them improved tensile strength for demanding applications. Wiseco designed these for builders who are pushing their engines hard, whether that's on the track or in a severe duty street build.

You'll find precision machining throughout, including the ring grooves, anti-detonation grooves, and features aimed at improving ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown and forced pin oiling are details that matter when you're aiming for maximum durability and performance under extreme conditions. This set includes eight pistons, ready to be installed in your LS engine.

Because these are built for heavy-duty racing, they are not CARB approved and cannot be shipped to California. Make sure to consult your engine builder or the manufacturer's instructions for proper installation and any other components you might need for your build.
