These hooks are robust and made from Titanium. They weigh only 3.4 grams and will hold up to 1000 pounds. They replace the whoopie bead with a hook that will “snap” on to 7/64ths amsteel. They are easy to connect, easy to disconnect but will stay on until you unhook them They create a waterbreak and make it so you can store your wet suspension separately. It is not recommended to use whoopie hooks with anything but 7/64ths Amsteel.
