Carry high-pressure fluid from the power steering pump to the hydroboost unit with the Sunsong power steering pressure line hose assembly (MPN 3404137). This pump-to-hydroboost line drops in as a direct-fit replacement for the 2014-2019 RAM 2500, 2014-2019 RAM 3500, 2014-2018 RAM 4500 and 2014-2018 RAM 5500 — see the Buyer's Guide tab for engine-level fitment. If a cracked, chafed or leaking factory pressure line is behind your fluid loss or hard steering, this assembly replaces it.

  • Pre-assembled with brackets: ships ready to install, cutting labor time versus lines sold as separate hoses.
  • Built to high-pressure ratings: a 1,500 psi max working pressure, 8,700 psi burst rating and 1,600 lb tensile strength for durable, long-life service.
  • Factory pressure-tested: every pressure hose passes a high-pressure quality-assurance test before it leaves the plant.
  • Complete assembly: includes the additional components needed to restore the wearable parts to original condition.

From Sunsong, a vertically integrated manufacturer of automotive fluid-transfer hoses and lines, engineered for exact form, fit and function.
