Made to fit a 2.0 Tube so it is easily adjusted to fit larger or smaller in a couple of minutes. It, 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. Sometimes single tabs are the way to go but we didn't want them weaker than our 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. These are meant to be interchanged with our other sizes to attain the angle desired. these are 2.125" (2 1/8) from the axle to the bolt centerline. The bolt hole is drilled for .5625" (9/16) bolts but easily drilled to another size.
