Pfadt Racing is introducing a new line of racing suspension ball joints. Made in the USA of steel construction, our ball joints offer one less thing you need to worry about on your race car. The stud features a cotter pin for positive retention of the nut which is a huge improvement over messing around with an allen wrench and an oversized crush nut. Unlike the factory units, ours aren't ruined by the heat from your brakes, you won't have to wrap them in heat tape, and they're lash-adjustable so if you get any play you can adjust them.
