Wiseco Chevy LS Series -20cc R/Dome 1.110x4.005 Piston Shelf Stock Kit

When you're building a serious performance engine for your 1997-2004 Chevrolet Corvette, you need components that can handle the stress. This Wiseco Professional Series piston kit gives you a set of eight forged pistons, each featuring a -20cc reverse dome design and measuring 4.005 inches in bore diameter. These pistons are built for demanding applications where durability and performance are critical.

Wiseco crafts these pistons from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the rigors of racing and heavy-duty use. The machining process is precise, including anti-detonation grooves and features designed to improve ring seal, which helps maintain compression and prevent blow-by. They also come with an ArmorGlide skirt coating that reduces friction and noise while resisting seizure. The crown is fully machined, and the pistons feature forced pin oiling to ensure proper lubrication of the wrist pin.

This kit is designed for builders who are pushing their LS engines hard. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
