Keep high-pressure power steering fluid flowing from the hydroboost unit to the steering gear with the Sunsong Power Steering Pressure Line Hose Assembly 3403967. It installs as a direct-fit replacement on the 2011-2014 Chevrolet Express 2500, 3500 and 4500; the 2011-2014 GMC Savana 2500 and 4500; and the 2011-2016 GMC Savana 3500. This is the hydroboost-to-gear pressure line, delivering pressurized fluid to the steering gear so the hydraulic assist can do its job.

  • Hydroboost-to-gear routing: carries pressurized power steering fluid from the hydroboost to the steering gear on the listed vans.
  • Complete assembly: supplied as a line-and-hose assembly with its end fittings, so it drops in without piecing parts together.
  • Signs it may need replacing: power steering fluid leaking along the line or at a fitting, low fluid, or a whine/groan from the system. Diagnose the cause before replacing, since these signs can have other sources.
