SAF-Holland

This product family represents a flexible mounting platform designed to support standard fifth-wheel couplings with a focus on reliability and straightforward installation. The simplified feature set signals broad compatibility with a wide range of trailer configurations and tractor frames, making it suitable for mixed-fleet operations. The construction emphasizes a rigid interface that ensures accurate kingpin alignment and repeatable engagement under dynamic loading, contributing to consistent towing performance and reduced pin wear. The mounting approach commonly used in this category reduces interference with cab components while maintaining easy access for inspection and maintenance. VMRS code 059-001-045 anchors the item within the fifth-wheel base/bracket assembly group, ensuring compatibility with other kit components across fleets. Benefits include reduced lifecycle costs through modular compatibility, easier retrofits during fleet upgrades, and standardized spare parts across multiple truck models. In practice, operators will experience consistent engagement, improved trailer stability, and smoother decoupling under varying trailer lengths and road conditions. The category context reinforces its role in a broad, interchangeable family of mounting solutions for heavy-duty towing applications.
