The cups you need only work with this tool so it's not like you can use your current set, and that small cup set is $430.
Looks a lot more clumsy than the BJP1 and if I'm reading correctly the cups are only for Ford and Chevy trucks?
Actually from what I was told it's designed to be used with any ball joint cups.
i have done many a ball joint and few years ago i bought the bjp-1, what i like about the matco is you can press either direction, so the forcing screw can be either up or down depending on clearance for the impact gun. What i really like is both sides have a pass thru hole for the ball joint stud, so if you have a tall stud you dont have to have deep/ tall adapter for the clearance .
The c frame with 150lbs on the screw put out about 6000 pounds of force. 50lbs on the Matco screw put out over 7000 pounds. It's a nice piece. A little getting use to.
