XA-H12
Base
SAF-Holland

Designed for the fifth wheel hitch system, this foundational platform provides the precise interface between the tractor frame and the trailer coupling. Engineered to withstand high static and dynamic loads, the assembly blends robust alloy machining with tight tolerances to ensure square, consistent pin alignment under demanding road conditions. The centralized mounting surface supports compatible kingpin saddles and provides even load transfer across the wheelbase, reducing wear on related components and improving overall stability during coupling and uncoupling. With a VMRS code of 059-001-045, the part aligns with OEM maintenance documentation and fault-diagnostic workflows, aiding service technicians in parts replacement, inspection intervals, and wear analysis. In operation, the component serves as the anchor for various fifth wheel modules, enabling predictable articulation and proper tilt control. Category context places this item in the Fifth Wheel family, reinforcing its role as the primary interface element for towing applications. Practical benefits include improved load distribution, straightforward inspection of mounting holes and surface finish, and compatibility with standard mounting patterns across typical fleet equipment. When selecting a replacement, verify mounting pattern, pad thickness, and torque specification per OEM guidelines to ensure longevity and safe towing performance.
