5.0L Coyote Single Flanged Double Flanged Dry Cylinder Sleeve Kit

The Darton Sleeves 300-056-SF/DF is a high-performance dry cylinder sleeve kit engineered specifically for Ford 5.0L Coyote engines, allowing bore sizes from 90mm to 94mm. This comprehensive kit includes both single flanged (SF) and double flanged (DF) steel sleeves to accommodate various performance levels and building requirements. Key specifications include a bore diameter of 3.525 inches, an outside diameter of 3.825 inches, and a wall thickness of 0.150 inches. The sleeve length is 5.250 inches, with a flange thickness of 0.200 inches and a flange diameter of 4.073 inches. These sleeves are constructed from high-strength steel. Single Flanged (SF) sleeves feature a single flange at the top and are suitable for most performance applications, offering durability and sealing for street and moderate performance builds. Double Flanged (DF) sleeves have flanges at the top and bottom, providing additional stability and strength to prevent sleeve movement and distortion under high-stress conditions, making them ideal for high-boost, high-horsepower, or racing applications. This kit utilizes a dry sleeve design, installed with an interference fit. Darton recommends specific interference tolerances based on material combinations (iron to iron, or iron to aluminum blocks). Proper block preparation, including correct dimensional tolerances and surface finish, is essential for successful installation. Benefits include the ability to increase bore sizes for added displacement and power potential, reinforced cylinder walls for forced induction and high-RPM applications, and precision machining for accurate fitment and sealing.
