This is a set of 6, 2 each short, medium & long single Tab Links, they, and all of our Link Single Tabs are a seriously strong .375" (3/8) thick. We had to go that big to equal the strength of our .25" (1/4) paired link brackets . Use the ones you need and return the other 2 unused for a full refund or credit. This is for those of you that can't quite decide until they are in your hands. The ease of use of single tabs this thick sometimes make them a better choice for your 3 or 4 link suspension & its easy to put a bridge between 2 to create the 4 link bracket you want.
