Wiseco RED Series Ford Small Block 4.005in Bore 1.090in CH -5.00 CC Piston Set

This is a set of eight Wiseco RED Series pistons, designed for Ford Small Block engines. You get the pistons themselves, precision-machined from 2618 aluminum for the tensile strength needed in demanding performance and racing applications. Each piston features a 4.005-inch bore, a 1.090-inch compression height, and a -5.00cc dish volume. The set also includes premium rings, so you won't need to source those separately.

Wiseco's Race Engineered Design (RED) process means these pistons are built with specific features to give you an edge. They have horizontal slot oiling in the pin bores to keep the wrist pin and connecting rod small end well-lubricated, which is crucial for a long service life under stress. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a low weight. You'll also find an accumulator groove that helps maintain consistent ring seal and power output. Plus, the ArmorGlide skirt coating is applied to reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall.

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, these pistons offer a well-built option with advanced features for durability and competitive performance.
