Wiseco RED Series Ford Small Block 4.000in Bore 1.165in CH -5.00 CC Piston Set

When you're building a Ford Small Block for serious performance, you need parts that can handle the stress. This piston set from Wiseco's RED Series is designed for just that. You get a complete set of eight pistons, ready to be installed in your 4.000-inch bore engine. These aren't your average pistons; they're forged from 2618 aluminum, a material chosen for its strength and durability under high-performance conditions, especially when you're running power adders like turbos or superchargers.

Wiseco's Race Engineered Design (RED) philosophy means these pistons are optimized for strength and weight. They feature a strutted design specific to the engine application, maximizing rigidity without adding unnecessary mass. You'll also find horizontal slot oiling in the pin bores, which is a smart detail that keeps the wrist pins and small-end of the connecting rods properly lubricated, crucial for keeping things running smoothly and extending service life. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also cutting down on wear to the piston skirts and cylinder walls. An accumulator groove is included to help maintain consistent ring seal and power delivery.

This set comes complete with premium rings, so you won't have to hunt for compatible ones separately. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Ford Small Block, this Wiseco RED Series piston set offers a well-built foundation for serious power.
