Wiseco RED Series Ford Small Block 4.000in Bore 1.090in CH -5.00 CC Piston Set

If you're building a Ford small block engine for serious performance, these Wiseco RED Series pistons are a solid choice. They're forged from 2618 aluminum, which is known for its tensile strength, making them well-suited for high-stress applications like drag racing or circle track. The Race Engineered Design (RED) process means they're not just strong, but also precisely machined for a competitive edge.

Wiseco has put some thoughtful details into these pistons. The horizontal slot oiling in the pin bores helps keep the wrist pins and small ends of the connecting rods well-lubricated, which is crucial for keeping things running smoothly and extending the life of your engine components. Each set includes premium rings, so you won't have to hunt for those separately. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also helping to cut down on skirt and cylinder wear. An accumulator groove is also included to help maintain consistent ring seal and power delivery.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for specific Ford small block applications with a 4.000-inch bore.
