Rebuild Kit, Mounting Bracket
SAF-Holland

Precision rebuild kit for mounting bracket in heavy-duty fifth wheel couplers is engineered to restore critical alignment, clamp integrity, and load-path continuity after wear or impact. This kit provides the essential components—fasteners, bushings, reference surfaces—that reestablish OEM geometry, ensuring a secure interface between the kingpin assembly and the bracket. By replacing worn hardware and degraded surfaces, technicians reduce side-to-side play, prevent binding under articulation, and maintain smooth coupling behavior during engagement, braking, and rough-road operation. The design reflects typical fifth-wheel requirements and is sized to support standard towing and payload demands, delivering consistent clamping force and repeatable engagement across a wide range of trailers. With VMRS 059-001-021, it aligns with standardized maintenance coding used in fleet service programs, enabling precise reporting and budgeting. Practical benefits include simpler service intervals, lower risk of misalignment-induced wear, extended bracket life, and improved safety margins at the hitch interface. In daily operations, fleets experience steadier couplings, reduced bracket wear, and predictable performance in load transfer during dynamic events such as turns and braking. This rebuild approach supports preventative maintenance that minimizes downtime and extends component life in demanding on-highway and vocational applications.
