These are a great way to do alot of things! They can be used as a Shock Tab, a Link Tab, a Limit Strap Tab, the list goes on. they are made from .188 sheet but I see the complete tube wrap adding a ton of resistance to tear off which has been the reason for larger tabs til now. They are sold in pairs and 3 different tube sizes, 1.5", 1.75", & 2". The holes are .505" so you can get a stout bolt through them and drill them bigger easily. They are sold in pairs.
