• Male O-ring fittings: 16 mm end 1 and 18 mm end 2
• 39 in. overall length for the specified steering layout
• CSM hose material for pressure-line service
• High-grade steel tubing with zinc electroplating for corrosion resistance
• Pressure tested before shipment for installation confidence

Built To OE-Level Specifications

Sunsong 3404137 is a power steering pressure line hose assembly made for the hydraulic steering circuit on Ram heavy-duty trucks. It is designed around the original routing from the pump to the hydroboost unit, with exact-fit dimensions and male O-ring connections to match the listed vehicle applications. The hose assembly is manufactured to exceed original equipment performance standards with a 1,500 psi maximum working pressure, 8,700 psi burst pressure rating, and 1,600 lb tensile strength.

This part cross-references Dorman - HELP 80940 and Gates 352545 for the same application. If you are replacing a leaking or damaged Ram 2500 power steering pressure hose or Ram 3500 pump-to-hydroboost line, 3404137 provides a direct replacement path for the listed trucks.

Common Problems This Hose Can Address

• Power steering fluid leaks at the pressure line
• Loss of steering assist from a damaged hose
• Corrosion on the original steel tubing
• Cracked or hardened hose material from age and heat
• Fitment issues caused by an incorrect replacement line

Installation Notes

Confirm the vehicle uses the pump-to-hydroboost configuration before ordering. Match the 16 mm and 18 mm male O-ring ends to the original connections, and verify the 39-inch length against the factory routing on the truck. Inspect related seals, brackets, and mounting points during service so the new hose seats correctly and the steering system can be bled after installation.

Quality Assurance

Each Sunsong pressure hose is high-pressure tested at the factory before it leaves production. The steel tubing is zinc electroplated to help resist rust and corrosion from humidity, road salt, water, and grime, supporting long-term service on Ram 2500 and Ram 3500 steering systems.
