Detailed Product Description

This Sunsong power steering pressure line hose assembly (part number 3402544) features 16mm banjo fittings on both ends, providing a leak-resistant and secure connection to the power steering pump and steering gear. The hose is made from chlorosulfonated polyethylene (CSM), a material known for its resistance to heat, oil, and abrasion, which is critical for maintaining system integrity under high pressure. With a length of 99 inches (2514 mm), this hose assembly is tailored to fit the hydraulic routing of Lexus GS400, GS430, and SC430 models without the need for modifications. The absence of a bracket simplifies installation and reduces potential points of failure.
