Wiseco RED Series Ford Small Block 4.005in Bore 1.165in CH -5.00 CC Piston Set

If you're building a high-performance Ford Small Block engine, especially for demanding applications like drag racing 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 serious power, combined with precision machining for a competitive edge.

These pistons are forged and machined right here in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're adding power adders or pushing your engine hard. Wiseco includes a lot of smart features to help these pistons perform and last. You'll find horizontal slot oiling in the pin bores to keep the wrist pins and small ends well-lubricated, which is key for long service life. The dedicated forgings allow for an engine-specific strutted design, meaning they're optimized to be strong without adding unnecessary weight. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also cutting down on skirt and cylinder wear. This set comes complete with premium rings, so you won't have to source those separately, and an accumulator groove helps maintain consistent ring seal and power delivery.

This set is designed for a 4.005-inch bore with a 1.165-inch compression height and a -5.00cc dish. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
