These Ultra 100 axle link mount brackets are made to be welded directly to the axle tube. These brackets are manufactured from 3/16 100,000 min yield steel, CNC bent, laser cut and made to take serious abuse. These brackets also have added material to the axle side of the bridge, this reaches the axle tube so that you can weld both around the axle tube and across it. Perfect for a three link or four link suspension system. These are made to be attached to your axle and have an inside width of 2 5/8" or 2" for heims with misalignment spacers installed. We offer three different mounting angles so that you can mount your suspension joints in a neutral position to maximize axle articulation. Both widths have a 5/8" bolt hole.
