Wiseco Chevy LS 5.3 Series +6cc Dome 3.800in Bore Shelf Piston Kit - Set of 8

When you're building a high-performance Chevrolet LS engine for serious racing or heavy-duty applications, the pistons are a critical component. This Wiseco Professional Series piston kit is designed to handle the extreme demands of severe duty race builds, offering a significant upgrade over stock components. Each piston features a +6cc dome and a 3.800-inch bore, specifically tailored for the popular LS 5.3L platform, helping to achieve a desired compression ratio for increased power.

These pistons are forged from 2618 aluminum right here in the USA, a material chosen for its improved tensile strength under high stress. Wiseco machines them with precision ring grooves, anti-detonation grooves, and other features to ensure excellent ring seal, which is vital for both power and engine longevity. They also come with an ArmorGlide skirt coating that reduces friction, helps prevent seizure, and contributes to quieter operation. The fully machined crown and forced pin oiling further enhance their durability and performance under extreme conditions.

This set includes eight pistons, along with premium rings, ready for your engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust LS engine build intended for severe duty, this Wiseco kit offers a well-built foundation.
