Wiseco RED Series Ford Small Block 4.040in Bore 1.280in CH -22.00 CC Piston Set

If you're building a high-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 just that. They use a Race Engineered Design to give you the strength and durability required for demanding applications, along with precision machining for a competitive edge.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing serious power or using forced induction. To further enhance performance and longevity, they feature horizontal slot oiling in the pin bores. This design ensures optimal lubrication for the wrist pin and the small end of the connecting rod, which is vital for keeping things cool and preventing wear under extreme conditions. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. Plus, each set comes complete with premium rings, so you won't need to source those separately.

Wiseco also includes an accumulator groove to help maintain consistent ring seal and power delivery. The ArmorGlide skirt coating is applied to reduce operating friction and noise, which also helps minimize skirt and cylinder wear. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
