Description

The Thermo King 55-5920 U-bolt 6-pack contains genuine, OEM structural fasteners engineered specifically to provide maximum clamping force and physical stability within transport refrigeration units. Each factory-grade bolt in this part number 55-5920 package is manufactured to withstand structural shifting, extreme road shock, and high-frequency diesel engine vibrations typical of long-haul fleet environments. Commonly deployed to lock down frame framing, exhaust lines, or under-mount accessories on SB-series trailer reefers, these heavy-duty fasteners maintain structural integrity across challenging terrain. By utilizing an authentic direct-fit kit instead of low-tier hardware, fleet managers actively reduce unexpected component rattling, stress fractures, and expensive on-road cargo failures. [1, 2]
⭐ Key Features & Benefits
  • OEM High-Tensile Steel: Forged to original Thermo King engineering criteria to guarantee exact tensile strength, pitch spacing, and operational reliability. [1]
  • Anti-Vibration Clamping: Specially calibrated to resist continuous diesel harmonic frequencies, eliminating bracket shifting and bolt backing.
  • Corrosion-Resistant Coating: Shielded with industrial plating to survive prolonged exposure to rain, snow, road salt, and harsh under-chassis elements.
  • Structural Safety Assurance: Provides critical load distribution across mounting surfaces to prevent fatigue cracking on vulnerable reefers.
  • Convenient 6-Piece Fleet Bundle: Packaged in a practical, multi-unit shop quantity to replace old or stretched hardware during full unit overhauls.
🔧 Uses / Applications
  • SB Trailer Reefer Framework: Specifically optimized for securing internal frame, casing, and bracket assemblies on Thermo King SB-series trailer units.
  • Exhaust & Support Piping: Ideal for anchoring vibrating high-temperature exhaust stacks or structural lines safely to the main chassis frame.
  • Fleet Preventative Maintenance: Perfect replacement hardware kit during regular engine compartment or undercarriage system overhauls.
  • Severe Duty Route Operations: Recommended for commercial reefers traversing rough distribution yards or high-mileage highway corridors. [1, 2]
