Installation Notes and Tips

Verify the vehicle is not equipped with Hydroboost where the fitment notes exclude it. Match the 5/8 in. male inverted flare and 11/16 in. male inverted flare ends, along with the 39.3 in. overall length, before installation. Inspect adjacent steering components, fittings, and sealing surfaces for wear or corrosion so the new hose can seat correctly and operate without leaks.

Quality Assurance

Each Sunsong pressure hose is pressure-tested before leaving the factory. The assembly is built to exceed original equipment performance standards with a 1,500 psi maximum working pressure, 8,700 psi burst pressure rating, and corrosion-resistant steel tubing for long service life.
