Detailed Product Description and Specifications

The Sunsong 3402859 power steering pressure line hose assembly is built with high-quality chlorosulfonated polyethylene (CSM) hose material, known for its resistance to heat, oil, and abrasion. This 37.7-inch (958 mm) hose features an 18 mm male o-ring fitting on one end and a 16 mm female o-ring fitting on the other, ensuring a secure and leak-free connection within the power steering system. The absence of a bracket and power steering switch port simplifies installation and compatibility with the specified Dodge Ram 2500 and Ram 3500 models. This hose assembly is engineered to maintain consistent hydraulic pressure, contributing to smooth and responsive steering performance under demanding conditions.

Installation Notes and Technical Tips

When installing the Sunsong 3402859 power steering pressure line hose assembly, ensure the fittings are properly aligned to avoid cross-threading. The hose length of 37.7 inches (958 mm) is designed for direct replacement on compatible Dodge Ram 2500 and Ram 3500 models. No bracket is included, so verify existing mounting points before installation. The hose does not include a power steering switch port, so it is intended for systems without this feature.
