Wiseco Chevy LS Series -20cc R/Dome 4.125inch Bore Piston Shelf Stock

If you're building or rebuilding a Chevrolet LS engine for serious performance, these Wiseco pistons are a solid choice. They're designed to handle the demands of heavy to severe duty applications, whether you're racing or just pushing your engine hard. The -20cc dish in the dome helps achieve a specific compression ratio when paired with the right cylinder heads and crankshaft, making it a key component for tuning your engine's power output.

Wiseco forges these pistons from 2618 aluminum, a material known for its improved tensile strength, which is crucial for components that experience high stress and heat. The pistons also feature precision ring grooves, anti-detonation grooves, and other ring seal improvements to ensure a tight seal and efficient combustion. You'll also find an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure, keeping your engine running smoothly and quietly under load. The fully machined crown and forced pin oiling further contribute to their durability and performance.

These pistons fit a wide range of popular LS-powered vehicles, including models like the Cadillac CTS, Chevrolet Camaro, and Pontiac GTO. Remember that these are not CARB approved and cannot be shipped to California.
