Lock and Pins Kit (XA-311)
SAF-Holland

This locking and pin assembly is engineered for heavy-duty fifth-wheel coupling systems, delivering secure engagement and controlled release at the kingpin interface. The design concentrates on precise fit and robust detent retention to minimize unintended decoupling events during high-vibration highway duty. By integrating a durable locking pin set with compatible retainers and actuating elements, this kit supports reliable one-hand or controlled-access operation, which translates into safer coupling and easier maintenance in the field. Classified under VMRS 059-001-010, it sits within the locking and latching family of components and corresponds to category 42784, which aligns with standard fifth-wheel lock hardware used across multiple OEM configurations. The inclusion of a Fifth Wheel family attribute highlights its intent for common kingpin coupling platforms, ensuring broad compatibility with typical skid and tractor combinations. Practical applications include trucking and heavy-haul operations where uptime and secure tethering are critical; technicians can rely on this kit for routine servicing, wear compensation, and preventive replacement to maintain smooth latch action and long service life. Cross-references and related maintenance data support accurate identification during inventory planning and repair planning, helping fleets minimize downtime and optimize maintenance cycles.
