This unit is plug and play, but it is strongly recommended you replace the hydraulic line o-rings during installation. Your old o-rings may also get stuck in your old cylinder, so if you are reusing them, make sure they are installed correctly to prevent further leaks. If you have any questions regarding installation if this part, or any other issues you're experiencing with your convertible top, feel free to message me, I'm happy to help in any way I can.
