Wiseco Chevy FULL ROUND +12.3 4040A Piston Shelf Stock

Wiseco is known for making strong, reliable internal engine components, and their Professional Series pistons are a prime example. If you're building a performance engine that needs to handle serious stress, these pistons are designed to do just that. They're forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength over other materials, making them a solid choice for heavy-duty race applications.

These pistons feature an ArmorGlide skirt coating that helps reduce friction and noise, while also making them more resistant to seizing. The crown is fully machined, and the ring grooves are precisely cut with anti-detonation features and additional sealing improvements to ensure a good seal between the piston and cylinder wall. Plus, they come with forced pin oiling to keep the wrist pin properly lubricated under high loads. This piston fits a wide range of Chevrolet Small Block engines, including models like the Camaro, C10 Pickup, and C1500.
