Rubber Cushion Mounting Bracket Pin Kit
SAF-Holland

Engineered mounting assemblies play a pivotal role in isolating the tractor trailer interface from road induced shock. This complete rubber cushion mounting set provides a resilient interface between the fifth wheel mounting bracket and the vehicle frame, absorbing vibrations and reducing dynamic stress at the kingpin. The combination of elastomer cushions, pins, and mounting hardware enables precise alignment while resisting load transfers that would otherwise accelerate wear on hitch components and related linkages. By restoring or replacing worn cushions the system preserves proper engagement, minimizes clatter, and lowers maintenance frequency for the fifth wheel assembly. The included kit supports standard installation patterns used in most heavy duty fleets, and its VMRS classification identifies it as a serviceable replacement under 059-001-004. This part is particularly valuable during scheduled maintenance and after service on rough highways where cushion wear is common. Its importance extends to safety as consistent cushion performance helps maintain smooth towing forces, improves ride quality, and reduces fatigue on the mounting points. Category context indicates it belongs to the fifth wheel subsystem family, reinforcing its role in cab trailer coupling.
