Installation Notes and Tips

Verify the end fittings, hose length, and routing before installation. This assembly uses a 7/16 in. female inverted flare on one end and a 7/16 in. male O-ring on the other, so matching the connection style is important for proper sealing. Confirm the vehicle is equipped with hydroboost and skid control as listed in the fitment data.
