Wiseco BBC Quick 16 +42cc Dome 1.155inch Piston Shelf Stock

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance builds. The 2618 alloy offers improved tensile strength over other aluminum types, making it a solid choice for engines that see heavy or severe duty. This particular piston features a +42cc dome, which is designed to work with specific cylinder head volumes to achieve a desired compression ratio. The crown is fully machined, and the piston includes precision ring grooves, an anti-detonation groove, and features for additional ring seal, all aimed at improving performance and durability under demanding conditions.

Wiseco also incorporates an ArmorGlide skirt coating on these pistons. This coating helps reduce friction, resist seizure, and contribute to quieter operation, especially during the critical break-in period and under high stress. The forced pin oiling design ensures the piston pin receives adequate lubrication, which is crucial for longevity in high-performance applications. These pistons are designed and built in the USA, reflecting a commitment to quality construction for racing and performance builders.
