Wiseco Chevy LSX 5.3 Series +6cc Dome 3.790in Bore Shelf Piston Kit - Set of 8

If you're building a high-performance Chevrolet LS engine for serious racing or severe duty applications, this Wiseco Professional Series piston kit is designed to handle the extreme demands. These pistons are forged from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the high pressures and temperatures found in competitive racing environments. Each piston is precisely machined in the USA to ensure accuracy and consistency.

Wiseco has packed these pistons with features aimed at maximizing performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is crucial for maintaining compression and preventing blow-by under heavy load. The fully machined crown ensures a consistent combustion chamber volume, and the forced pin oiling helps keep the wrist pins properly lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and contribute to quieter operation, all important factors when pushing an engine to its limits.

This kit includes eight pistons, each with a +6cc dome and a 3.790-inch bore, designed to work with your specific LSX 5.3L engine build. Remember that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build that can withstand severe duty, this Wiseco kit offers a solid foundation.
