Wiseco RED Series Ford Small Block 4.000in Bore 1.280in CH -22.00 CC Piston Set

What you get in this kit are eight forged pistons designed for Ford Small Block engines. These are the RED Series pistons from Wiseco, featuring a 4.000-inch bore and a 1.280-inch compression height, with a -22.00cc dish volume. They're built from 2618 aluminum, a material chosen for its tensile strength, making them well-suited for high-performance racing and applications that use power adders like turbochargers or superchargers.

Wiseco's Race Engineered Design (RED) philosophy means these pistons are precision-machined to give you a competitive edge. You'll find horizontal slot oiling in the pin bores, which is a smart way to keep the wrist pin and the small end of the connecting rod properly lubricated, helping to ensure a long service life. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping the weight down. Plus, each set comes complete with premium rings, so you won't need to source those separately. They also feature an accumulator groove to help maintain consistent ring seal and power delivery.

These pistons also come with an ArmorGlide skirt coating. This isn't just for looks; it helps reduce friction and noise during operation, and it also cuts down on wear to both the piston skirt and the cylinder wall. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are also subject to California's Prop 65 warning.
