Wiseco RED Series Ford Small Block 4.000in Bore 1.280in CH -5.00 CC Piston Set

Starting with the 2618 aluminum construction, these Wiseco RED Series pistons are built for the demands of performance racing and engines with power adders. The Race Engineered Design (RED) philosophy means these pistons aren't just strong, they're precisely machined to give you an edge. They're made in the USA, so you know you're getting a well-built part for your Ford Small Block build.

You'll find horizontal slot oiling in the pin bores, which is a smart detail that keeps your wrist pins and the small end of the connecting rods well-lubricated, crucial for keeping things running smoothly over the long haul. Wiseco uses dedicated forgings for each engine application, allowing them to create an optimized strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also helping to cut down on wear on both the piston skirts and the cylinder walls. Each set comes complete with premium rings, so you don't have to source those separately.

An accumulator groove is also included, which helps maintain consistent ring seal and power delivery. These pistons are designed for popular domestic V8 platforms, making them a cornerstone for everything from drag racing to circle track applications. Keep in mind these are not CARB approved and cannot be shipped to California.
