Thick wall DOM steel tubing is the most common material of choice for making steering links, but 7075 solid aluminum links are available as well and tend to spring back to shape more when bowed under load. Thread taps are available in sizes for common tie-rod ends and spherical rod ends. The normal practice of threading one end of the tube with right-hand threads and the other end for left-hand threads allows for easier link adjustments on the vehicle. However, using right-hand threads on both ends reduces tool costs and means less unique trail spares to carry. There are pros and cons to each approach.
