- Pre-assembled with brackets: ships ready to install, reducing labor time compared to replacement versions sold as individual hoses.
- Precision engineered to fit: includes the additional components needed to restore the wearable parts to original condition.
- High-pressure rated: pressure hoses carry a max working pressure of 1,500 psi, a burst pressure rating of 8,700 psi, and a tensile strength of 1,600 lb.
- Factory-tested: every pressure hose is subjected to a high-pressure quality assurance test before leaving the factory.
If a cracked, leaking, or deteriorated pressure line is the cause of hard steering, whining, or fluid loss, this assembly replaces it. Sunsong specializes in automotive fluid-transfer hoses and lines built to exact form, fit, and function.
