Detailed Description

Sunsong 3405254 is a direct-fit pressure hose assembly for Ram 2500 and Ram 3500 trucks equipped with hydroboost steering systems. It is designed for the pump to hydroboost connection and uses application-specific end fittings to match the original routing requirements. This part cross-references Dorman - HELP 80944 and Gates 352549 for the same application.

The hose construction combines durable tubing with corrosion-resistant zinc plating to help maintain performance in harsh underbody conditions. The assembly is factory tested under high pressure before shipment to support consistent operation after installation. For Ram 2500 and Ram 3500 owners replacing a worn or leaking steering line, 3405254 provides a service-ready replacement built around the original hydraulic layout.

Common Problems This Part Can Help Solve

  • Power steering fluid leaks at the pressure line
  • Loss of steering assist from a damaged hose
  • Cracked, corroded, or fatigued hydraulic tubing
  • Improper hose routing on hydroboost-equipped trucks
  • Pressure loss caused by worn fittings or line failure

Installation Notes and Tips

Verify hydroboost system configuration before ordering, since this hose is specified for pump to hydroboost routing on 2013-2018 Ram 2500 and Ram 3500 models. Confirm end fitting sizes and connection style during removal to ensure proper alignment with the existing hydraulic system.

Inspect adjacent brackets, seals, and mounting points for wear before installing the new hose. Clean the connection areas thoroughly to help reduce contamination in the power steering circuit and to support a proper seal at the fittings.

Quality Assurance

Each Sunsong pressure hose is pressure tested at the factory before it leaves production. The hose is engineered to exceed original equipment performance standards for pressure capacity and durability, with corrosion-resistant steel tubing intended to support long service life in demanding driving conditions.
