Wiseco Chevy LS Series 12cc Dome 1.300 x 4.030 Piston Shelf Stock Kit

Starting with pistons forged from 2618 aluminum, these Wiseco Professional Series pistons are built for serious performance in your Chevrolet LS engine. The 4.030 inch bore size and 1.300 inch compression height are specific dimensions that matter when you're rebuilding or upgrading your engine for heavy or severe duty use. These aren't just off-the-shelf parts; they're designed with features like precision ring grooves, anti-detonation grooves, and forced pin oiling to ensure reliability under demanding conditions.

Wiseco machines these pistons in the USA, and the fully machined crown features are a testament to their attention to detail. You'll also find an ArmorGlide skirt coating applied, which helps reduce friction and noise while also resisting seizure. This coating, combined with the 12cc dome volume, contributes to improved combustion efficiency and durability, making them a solid choice for builders who push their engines hard. The set includes premium rings designed to work seamlessly with the pistons for optimal sealing.

This set is intended for builders who need robust components for high-performance applications. Please 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.
