Detailed Product Description

The Sunsong 3402289 power steering pressure line hose assembly is built to meet the hydraulic requirements of heavy-duty trucks and vans such as the Chevrolet Express and GMC Savana series, 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 demanding conditions. Both ends of the hose feature male o-ring fittings—16mm on one end and 18mm on the other—ensuring a secure, leak-resistant connection to the power steering pump and steering gear. With a length of 43.8 inches (1112 mm), this hose assembly fits the specified vehicle models without the need for additional brackets or power steering switch ports.
