Detailed Description

Dayco 5061265 is a serpentine belt for accessory drive systems that require a long, 6-rib K-section belt. The EPDM rubber compound helps maintain belt performance under heat and cold cycling, while aramid reinforcement adds tensile support for demanding main drive use. This belt is listed for Ford E-350 Super Duty, Ford F-250 Super Duty, and Ford F-350 Super Duty applications with a Deweze hydraulic pump, including 2006-2010 Ford E-350 Super Duty main drive setups and 2006-2010 Ford Super Duty truck configurations noted in the fitment data. This part cross-references Gates (e.g., K061265) for the same application.
