Rebuild Kit XA-2801-AX-1
SAF-Holland

This rebuild kit is designed to restore the functional integrity of a XA 2801 AX style assembly within the fifth wheel family. It provides a targeted set of wear parts needed to reestablish the intended clearances and tracking that govern accurate kingpin seating and load transfer. The kit adheres to the VMRS 059-001-032 designation, enabling consistent maintenance planning and part numbering across fleets and service shops. Classified under the broad fifth wheel category, it supports maintenance programs that emphasize repeatable performance and long service life in demanding trailer operations. Practical applications include midlife rebuilds during scheduled maintenance or after components exhibit wear that affects coupling reliability. The lack of listed cross references indicates this is a standalone rebuild option compatible with assemblies within the same family group. Benefits include longer service intervals, improved mating surface condition, and a return to factory-like coupling precision, all of which contribute to safer, more efficient operations.
