Wiseco RED Series Ford Small Block 4.040in Bore 1.230in CH -5.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components for performance applications. This RED Series piston set is built for Ford Small Block engines and uses Race Engineered Design (RED) principles to give you a competitive edge. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, giving them the tensile strength needed for serious racing and power adder setups.

What sets these pistons apart is the attention to detail. They feature horizontal slot oiling in the pin bores to keep your wrist pins and connecting rod small ends properly lubricated, which is crucial for a long service life under stress. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also cutting down on skirt and cylinder wear. You also get premium rings included with each set, so you don't have to hunt for compatible ones.

An accumulator groove is included to help maintain consistent ring seal and power delivery. This set is designed for a 4.040-inch bore with a 1.230-inch compression height and a -5.00cc dish. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
