It is a direct-fit replacement for applications such as the Chevrolet Blazer, Chevrolet K5 Blazer, Chevrolet C10, GMC Jimmy, and GMC C1500 Suburban in the listed years. Sunsong 3402120 is built to restore proper steering pressure routing on classic GM trucks and SUVs with pump-to-hydroboost plumbing.\u003c\/p\u003e\u003cp\u003eThe hose assembly is manufactured to exceed original equipment performance standards and uses corrosion-resistant steel tubing with a zinc coating to help withstand humidity, road salt, water, and grime. The pressure hose is precision engineered for the listed fitments and is factory tested for pressure integrity before release.\u003c\/p\u003e\u003cp\u003eThis part cross-references Four Seasons 55123 and Gates 366850 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Fix\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePower steering fluid leaks at the pressure line\u003c\/li\u003e\n\u003cli\u003eLoss of steering assist from a damaged hose\u003c\/li\u003e\n\u003cli\u003eCracked, rusted, or fatigued pump-to-hydroboost line sections\u003c\/li\u003e\n\u003cli\u003eIncorrect hose routing on hydroboost-equipped GM trucks and SUVs\u003c\/li\u003e\n\u003cli\u003ePressure loss caused by worn O-ring end connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the end sizes before installation: 16 mm male O-ring on one end and 18 mm male O-ring on the other. Confirm the vehicle uses a pump-to-hydroboost configuration, since this hose is not for standard steering gear routing. Inspect mating seals, brackets, and nearby lines for wear before installing the new hose.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eSunsong subjects each hose to high-pressure testing before it leaves the factory.
