This truss is made just for your Dana 80. Our truss is made from 1/4" and if you add more material to the top it just makes it harder to keep the rig low to achieve a low center of gravity. With the increased foot print of our trusses they will also add structural rigidity to your axle and help prevent your axle from bending and warping. This truss system was designed on our state of the art 3D CAD software, laser cut and bent with a CNC Press Brake. Like all of our products our trusses are made from high-strength American plate steel. If you shop around you will find that our truss systems are the best product for your four and three link suspension needs. Due to variations in castings some grinding may be required during installation.
