Wiseco Chevy Small Block 4.040in Bore 1.550in CH 13.50 CC Piston Set

If you're building a high-performance Chevrolet small block engine for serious racing or heavy-duty applications, these Wiseco Professional Series pistons are a solid choice. They're designed from the ground up to handle the extreme demands of competition, offering a significant step up from stock components. With a 4.040-inch bore and a 13.50cc dish volume, they're intended for builds where power and durability are paramount.

Wiseco crafts these pistons from 2618 aluminum right here in the USA, a material known for its improved tensile strength, which is crucial for withstanding high combustion pressures and temperatures. You'll find precision ring grooves, an anti-detonation groove, and other features designed to enhance ring seal and prevent detonation. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pin lubricated under extreme conditions.

This set includes eight pistons, ready for your next engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, always refer to the manufacturer's installation instructions and recommended assembly procedures.
