Detailed Product Description

The Sunsong 3402892 power steering pressure line hose assembly is built to maintain optimal hydraulic pressure in the power steering system of select Chevrolet and GMC heavy-duty trucks. The hose features a robust CSM (chlorosulfonated polyethylene) material that offers excellent resistance to heat, ozone, and hydraulic fluids, ensuring durability and longevity. Both ends of the hose are equipped with male o-ring fittings—16 mm on one end and 18 mm on the other—to provide a leak-free seal and secure attachment to the power steering pump and steering gear. With a length of 37.2 inches (944 mm), this assembly matches OEM specifications for a direct fit without modification. The absence of a bracket simplifies installation and reduces potential points of failure.
