Like all of the BTF laser-cut link brackets, the BTF 1 3/4 Tube 4 Link Bracket is laser-cut from 5/16 thick high-strength steel plate. This bracket measures 1 1/2 from the edge of the tube to the center of the bolt hole to accomodate the largest of suspension joints. The bolt hole size is laser cut to 5/8 but could be drilled up to 1 if necessary. This bracket is also a good part to use for mounting a transfer case, or engine to tube frame rails.
