Description

The Darton 300-056-DF is a set of double flanged (DF) wet cylinder sleeves designed for Ford 5.0L Coyote engines. These sleeves are constructed from ductile iron with a tensile strength of 130,000 psi, offering improved block integral strength and cast iron performance in an aluminum block. They feature "Swirl Coolant Technology" for enhanced heat dissipation and a phosphate coating for corrosion and rust resistance, which also protects O-rings.

The DF design provides additional stability and strength with dual flanges to prevent movement and distortion under high-stress conditions, making them suitable for high-boost and high-horsepower applications. The sleeves have a 3.6-inch bore, a 3.825-inch OD, and a 5.25-inch length.
