XAS12360P
Base S/A-Stationary
SAF-Holland

This stationary base provides a robust mounting surface for fifth wheel couplers, forming the critical interface between the tractor frame and the trailer kingpin. Engineered to distribute dynamic, multi-axis loads across a stable footprint, it helps maintain precise coupling alignment under highway, off-road, and load-transfer conditions. The VMRS code identifies it as a pentultimate, fifth wheel related assembly component, ensuring compatibility with standard mounting patterns and bolt matrices used across heavy-haul applications. In practice, it contributes to reduced lateral movement, improved pin engagement, and consistent towing geometry, which translates to better ride quality, reduced wear on mating components, and lower maintenance intervals. The design also supports straightforward inspection and service of the surrounding frame areas, helping technicians assess wear and corrosion risk during routine maintenance. Note the Prop 65 warning included in the documentation; follow all safety guidelines when handling and installing to protect personnel. Within the warehouse, its category context places it squarely in the fifth wheel mounting ecosystem, making it a foundational piece for reliable coupling performance across tractor-trailer configurations.
