Wiseco RED Series Chevy Small Block 400 4.165in Bore 1.062in CH -24.00 CC Piston Set

If you're building a high-performance Chevy Small Block 400 for the track, whether it's for drag racing or circle track, you need components that can handle the stress. These Wiseco RED Series pistons are crafted to give you that strength and precision. They're designed to be a solid foundation for serious engine builds where durability and competitive performance are key.

Wiseco makes these pistons in the USA from 2618 aluminum, a material known for its tensile strength, which is crucial for engines running high power or with forced induction. They feature a Race Engineered Design (RED) that optimizes the piston's structure for maximum strength while keeping weight down. You'll also find horizontal slot oiling in the pin bores, which is a smart detail that keeps the wrist pin and small-end of the connecting rod well-lubricated, helping to ensure a long service life for these critical components. An accumulator groove is included to help maintain consistent ring seal and keep power delivery smooth.

This set comes complete with premium rings, so you won't have to hunt for compatible ones separately. Additionally, each piston has an ArmorGlide skirt coating. This isn't just for looks; it actively reduces friction and noise during operation, and it also helps cut down on wear on both the piston skirt and the cylinder wall. This attention to detail in materials and design means you're getting a well-built set of pistons ready for demanding use.
