Wiseco Chevy LS Series -25cc Dish 4.000inch Bore Piston Shelf Stock Kit

When you're building a serious LS engine for your 1997-2004 Chevrolet Corvette, you need parts that can handle the stress. This Wiseco Professional Series piston kit gives you a full set of eight pistons, complete with premium rings, pins, and locks, all ready to go into your engine. These aren't your average pistons; they're built from 2618 aluminum, forged and machined right here in the USA for improved tensile strength, which is crucial when you're pushing an engine hard.

Wiseco has packed a lot of smart features into these pistons to ensure they perform and last. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, meaning better compression and less blow-by. The piston crowns are fully machined for accuracy, and they come with forced pin oiling to keep the wrist pins well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, making for quieter operation and better durability under heavy loads. These are designed for severe duty performance applications, so you know they're built tough.

This kit is designed for a 4.000-inch bore and features a -25cc dish, which is important for setting your compression ratio. The compression height is 1.300 inches, and the pin diameter is 0.927 inches. Remember, these pistons are not CARB approved and cannot be shipped to California. If you're building an LS engine that needs to perform reliably under extreme conditions, this Wiseco kit is a solid choice.
