Detailed Product Description

The Sunsong 3402223 power steering pressure line hose assembly is built to meet the hydraulic demands of power steering systems in Chevrolet Express and GMC Savana vans, as well as the Silverado 2500. The hose is made from chlorosulfonated polyethylene (CSM), a material known for its resistance to heat, oil, and abrasion, which helps maintain system integrity under high pressure. Both ends feature male o-ring fittings—16 mm on one end and 18 mm on the other—ensuring a tight seal and compatibility with factory power steering components. The 50.8-inch length provides a precise fit without the need for modification. This assembly does not include a bracket or power steering switch port, aligning with original equipment specifications for the listed vehicle models.
