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. 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. 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.
