Borgeson double u-joints are machined in our factory on state of the art CNC equipment from solid billet steel, stainless steel or aluminum. Ongoing engineering and testing ensures our components meet or exceed current automotive production vehicle requirements. Any of our 4 Double D (a round shaft with two flats) sizes, 14 different spline size yokes, and the 94 and later Mustang V style can be combined to mate components from many different manufacturers. They operate at angles up to 70. For example, with our components, you could easily connect a GM column to a new Mustang rack and pinion or a Ford column to a Saginaw box. Similar to OEM u-joints, the staked needle bearing caps prevent loosening and adjustment malfunction.
