Wiseco RED Series Ford Small Block 4.005in Bore 1.280in CH -5.00 CC Piston Set

If you're building a performance Ford Small Block engine for serious racing, the Wiseco RED Series pistons are designed to handle the demands of high horsepower and extreme conditions. These aren't your average replacement pistons; they're built from the ground up for power adders and competitive racing, from drag strips to circle tracks.

Wiseco crafts these pistons from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard. They feature a dedicated forging process that allows for an optimized, engine-specific strutted design, meaning they get the strength they need without carrying extra weight. You'll also find horizontal slot oiling in the pin bores, a detail that ensures your wrist pins and the small end of the connecting rods stay well-lubricated, which is key for long-term durability under stress. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also helping to minimize wear on the piston skirts and cylinder walls.

This set comes complete with premium rings, so you won't have to hunt for compatible ones separately. An accumulator groove is also included to help maintain consistent ring seal and keep power delivery steady. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
