Wiseco Chevy LS Series -25cc Dish 4.070inch Bore Piston Shelf Stock Kit

If you're building a serious performance LS engine for your 1997-2004 Chevrolet Corvette, this Wiseco Professional Series piston kit is designed to handle the demands of heavy to severe duty racing. These pistons are engineered and forged in the USA from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for high-stress applications. The kit includes eight pistons, each with a -25cc dish, a 4.070-inch bore, and a 1.300-inch compression height, ensuring they fit precisely within your LS engine block.

Wiseco has packed these pistons with features to enhance both performance and durability. You'll find precision ring grooves, an anti-detonation groove, and additional features designed for improved ring seal, which is crucial for maintaining compression and power under extreme conditions. The fully machined crown ensures a clean combustion chamber, and the forced pin oiling helps keep the wrist pins lubricated. Additionally, the ArmorGlide skirt coating reduces friction and noise while providing resistance to seizure, helping your engine run smoother and last longer.

This kit is a solid option for builders who are pushing their LS engines to the limit. 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.
