Wiseco RED Series Ford Small Block 4.010in Bore 1.230in CH -5.00 CC Piston Set

Wiseco is well-known for its high-performance forged pistons, and their RED Series is built for the demands of racing and serious performance builds. This piston set is specifically designed for Ford Small Block engines with a 4.010-inch bore. They are forged from 2618 aluminum, a material chosen for its high tensile strength, making these pistons well-suited for the stresses of performance racing and applications using power adders like turbochargers or superchargers.

These pistons feature horizontal slot oiling in the pin bores, which is a smart detail that helps keep the wrist pin and the small end of the connecting rod properly lubricated. This is crucial for ensuring a long service life in a high-performance engine. The dedicated forgings allow Wiseco to create an engine-specific strutted design, which means they’ve optimized the piston’s internal structure to give you the best possible strength while keeping the weight down. You also get an ArmorGlide skirt coating, which works to reduce friction and noise from the piston skirt against the cylinder wall, and it also helps cut down on wear in both the skirt and the cylinder itself. Each set comes complete with premium rings, so you won't need to source those separately, and an accumulator groove is included to help maintain consistent ring seal and power output.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance applications and are a solid choice if you're building a Ford Small Block for drag racing, circle track, or any other high-output use.
