Wiseco Chevy LS 4.130in 1.165in CH -23.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds. The 4.130-inch bore size is a common upgrade for many Chevrolet LS engine applications, allowing for increased displacement and potential power gains. Wiseco machines these pistons in the USA, ensuring precise manufacturing for critical components like the ring grooves, which feature anti-detonation designs and additional sealing features to help maintain compression and prevent blow-by under extreme conditions.

Beyond the core strength of the forged aluminum, these pistons come with an ArmorGlide skirt coating. This isn't just for looks; it's designed to reduce friction between the piston skirt and cylinder wall, which can lead to quieter operation and improved durability by resisting seizure. The crown is also fully machined, and the design includes forced pin oiling to ensure the wrist pin receives adequate lubrication, a crucial detail for high-RPM, high-stress engine operation. This set includes eight pistons, along with premium rings, ready for a severe duty performance build.

When planning your build, remember that these pistons are not CARB approved and cannot be shipped to California. Ensure you have the necessary supporting components for a high-performance engine, such as appropriate connecting rods and a balanced rotating assembly, to take full advantage of these well-built pistons.
