Wiseco RED Series Ford Small Block 4.005in Bore 1.230in CH -5.00 CC Piston Set

This is a complete set of eight forged pistons from Wiseco's RED Series, designed for Ford Small Block engines with a 4.005-inch bore. You get the pistons themselves, precision-machined for performance, along with premium rings to ensure a proper seal. These pistons are built using Race Engineered Design (RED) principles, meaning they're crafted from strong 2618 aluminum to handle the demands of racing and power adder applications.

Wiseco uses dedicated forgings for these pistons, allowing them to optimize the strutted design for maximum strength while keeping weight down. To further improve performance and longevity, they feature horizontal slot oiling in the pin bores, which keeps the wrist pins and small-end of the connecting rods well-lubricated. Each piston also has an accumulator groove to help maintain consistent ring seal and power output. Plus, the ArmorGlide skirt coating is applied to reduce friction and noise, which also helps minimize wear on the piston skirts and cylinder walls.

These pistons are forged and machined right here in the USA. Keep in mind that this specific part number is not CARB approved and cannot be shipped to California. If you're building a performance Ford Small Block, this set is a solid option for serious power.
