Wiseco Chevy SB -32cc Dome 4.165in Bore Piston Shelf Stock Kit

If you're building a serious performance Chevrolet Small Block engine, these Wiseco Professional Series pistons are a solid choice. They're designed for heavy to severe duty race applications, meaning they can handle a lot of stress and power. The -32cc dome shape is specific to certain compression ratio targets, so make sure it matches your build's needs.

Wiseco forges these pistons from 2618 aluminum right here in the USA, which gives them improved tensile strength for durability under high loads. You'll also find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is crucial for power and engine longevity. They also come with an ArmorGlide skirt coating that helps reduce friction and resist seizure, making the engine run quieter and smoother, especially during break-in and under demanding conditions. The fully machined crown ensures accuracy and consistency across the set.

This kit includes a set of 8 pistons, each with a 4.165-inch bore diameter and a 1.125-inch compression height. The pin diameter is 0.927 inches. Remember, these pistons are not CARB approved and cannot be shipped to California. For optimal results, always refer to the manufacturer's installation instructions regarding proper clearances, ring gap, and assembly procedures.
