Rein OE Quality Hydraulic Suspension Line assemblies offer technicians an OE solution to no longer usable originals. These hose assemblies are built with OE zinc alloy coated carbon steel tubing and end fittings. The life expectancy of the Active Body Control (ABC) system is highly dependent on the condition of the circulating hydraulic fluid. Therefore, the hydraulic fluid should be changed regularly, and we highly recommend Pentosin CHF 11S power steering fluid for this service.
