Wiseco RED Series Ford Small Block 4.030in Bore 1.230in CH -5.00 CC Piston Set

If you're building a performance Ford Small Block engine for serious racing, like drag or circle track, you need pistons that can handle the stress. The Wiseco RED Series pistons are built for exactly that. They use what Wiseco calls Race Engineered Design, which means they're forged and machined right here in the USA from strong 2618 aluminum to give you the tensile strength needed for high-horsepower builds and power adder applications.

These aren't just strong; they're smart too. You'll find horizontal slot oiling in the pin bores, which is a key detail for keeping the wrist pin and small end of the connecting rod properly lubricated, helping them last longer under heavy use. The dedicated forgings mean Wiseco can optimize the strutted design for each specific engine, getting you the best strength-to-weight ratio possible. Plus, they come with an ArmorGlide skirt coating that cuts down on friction and noise, while also reducing wear on the piston skirt and cylinder wall. This set includes premium rings, so you won't have to hunt for those separately, and an accumulator groove helps maintain consistent ring seal for reliable power delivery.

This set is for a 4.030-inch bore with a 1.230-inch compression height and a -5.00cc dish volume. Keep in mind these are not CARB approved and cannot be shipped to California.
