BORGESON u-joints are machined in our factory on state of the art CNC equipment from steel, stainless steel and aluminum. On-going engineering and testing ensures our components meet or exceed current automotive production vehicle requirments. Any of our 3 "Double D" (a round shaft with two flats) yokes, 13 different spline size yokes, and our new '94 and later Mustang rack "V" yoke can be combined to mate components from many different manufacturers. They operate at angles up to 35 degrees. For example, with our components you could easily connect a GM column to a new Mustang rack an pinion or a Ford column to a Saginaw box. BORGESON needle bearing u-joints have the distinct advantage of lasting as much as 10 times longer than non-needle bearing joints. We recommond only needle bearing u-joints for vehicles that are used on the street.
