Low Lube Plates Kit
SAF-Holland

The low-lube plates kit features aluminum construction to deliver a lightweight, corrosion-resistant interface between the trailer plate assembly and the kingpin head. This design reduces friction during mating and uncoupling cycles, contributing to smoother operation and reduced wear on high-contact surfaces. VMRS 059-001-033 places the kit within lubrication-management and wear-reduction components, while category 42770 identifies it as part of the fifth-wheel plate family. The Fifth Wheel designation signals broad compatibility with common plate and pocket configurations used across mainstream highway tractors. Practically, operators gain improved hitching comfort, quicker cycle times in repetitive coupling environments, and enhanced uptime due to lower routine maintenance demands. This kit is particularly advantageous when upgrading older assemblies or building new fleets that prioritize longer service intervals and reduced maintenance costs.
