Fifth Wheel Lock Assembly Replacement Kit
SAF-Holland

This replacement kit for a high capacity fifth wheel lock assembly is engineered to restore secure kingpin engagement and consistent locking performance. The construction uses heavy duty steel materials designed to withstand repeated cycling and harsh loading conditions commonly encountered in long haul and regional operations. A key feature is a maximum load rating of 50,000 pounds, which highlights suitability for demanding applications and helps fleets meet safety and performance targets during coupling and uncoupling. The VMRS code 059-001-010 places it within a designated repair subset of fifth wheel components, ensuring proper durability and serviceability. The category context 42784 identifies its role as a critical locking mechanism replacement for the coupling system. Practical use includes routine maintenance, post wear inspection, and unit rebuilds where restoring the original locking geometry reduces wear on mating surfaces and minimizes the risk of accidental uncoupling. This kit supports technicians with a precise, ready-to-install solution that promotes reliability and safety in daily operations.
