Wiseco Chevy LS Series 4.010in Bore -3cc Dome Piston Kit - Set of 8

If you're building a high-performance Chevrolet LS engine for serious racing or heavy-duty applications, this Wiseco Professional Series piston kit is a solid choice. These pistons are designed to handle the extreme demands of severe duty builds, offering a significant step up from stock components. They feature a -3cc dome design, which is crucial for achieving specific compression ratios when paired with the right cylinder heads and head gaskets for your LS engine.

Wiseco crafts these pistons from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for the high pressures and temperatures found in racing engines. The machining process is meticulous, with precision ring grooves, anti-detonation grooves, and features designed to enhance ring seal for better combustion efficiency and durability. They also come with a unique ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and operate more quietly, all contributing to a more reliable and efficient engine under load. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins properly lubricated, a critical detail for longevity in high-stress builds.

This kit includes a full set of eight pistons, ready for installation in your LS engine. Remember 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, especially when dealing with critical engine components like pistons.
