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

Wiseco is well-known for making strong internal engine components for performance applications. These RED Series pistons are built using their Race Engineered Design process, which means they're made to handle the demands of racing and high-power engines. They are forged and machined right here in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is exactly what you need when you're pushing an engine hard, whether that's on the drag strip or the circle track.

What sets these pistons apart is the attention to detail. They feature horizontal slot oiling in the pin bores to keep the wrist pins and small-end connecting rods well-lubricated, which is crucial for keeping them alive under heavy load. The dedicated forgings are shaped specifically for the Ford Small Block engine, allowing for a strutted design that maximizes strength while keeping the weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, and it also cuts down on wear on both the piston skirt and the cylinder wall. You also get premium rings included with every set, so you don't have to hunt for compatible ones, and an accumulator groove is built in to help maintain consistent ring seal and power delivery.

This set is for an 8-cylinder engine with a 4.005-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.
