Wiseco RED Series Ford Small Block 4.040in Bore 1.165in CH -5.00 CC Piston Set

If you're building a high-performance Ford Small Block engine for racing, like drag or circle track, you need pistons that can handle the stress. Wiseco's RED Series pistons are built for exactly that. They use Race Engineered Design (RED) principles to give you the strength and durability required for demanding applications, along with precision features that help you get the most out of your engine.

These pistons are forged and machined right here in the USA from 2618 aluminum, a material known for its tensile strength, which is crucial when you're pushing serious power or using forced induction. Wiseco includes horizontal slot oiling in the pin bores to ensure your wrist pins and the small end of the connecting rods stay well-lubricated, which is key for a long service life. The dedicated forgings allow for an engine-specific strutted design, meaning they're built to be as strong as possible while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also cutting down on wear to the piston skirt and cylinder walls. You also get premium rings included with each set, so you don't have to hunt for compatible ones separately. An accumulator groove is also part of the design, helping to maintain consistent ring seal and power delivery.

This set is for an 8-cylinder engine with a 4.040-inch bore and a 1.165-inch compression height, featuring a -5.00cc dish. Please note that these pistons are not CARB approved and cannot be shipped to California.
