Screw type ball joints

January 20, 2012
Only thing I didn't like is the poorly fitting grease seal... it doesn't fit like the OEM ball joints, but for the cost it's had to beat this item. I wouldn't recommend for a daily driver, but for a low mileage hotrod driven toy just fine
Pros:
  • Can Withstand Use
Yes, I recommend this product.

Thread pitch What is the thread pitch of the body of this ball joint? I need to re-tap the sleeve after welding it to the control arm.

The "thread" on these ball joints are not any specific thread so finding a tap for your needs will be nearly impossible. For a little background as to why you will not find anything - Originally Chrysler designed ribs to provide extra retention when they pressed the ball joints into a smooth bore hole. The aftermarket has now started machining sleeves with a "thread" of sorts that allows the ball joint to be screwed into place but there are really no specifications that govern the ball joint or sleeve "threads" thus there has been little need for companies to create a tap to fix damaged threads.

Ball Joint Spacers Why would I need ball joint spacers I received in my mustang II suspension kit with these ball joints. Also i received these as upper and lower to use on tubular A frames in this kit is this correct?

I am not quite sure what you are referring to by ball joint spacers, however this ball joint is frequently used in tubular control arms (upper and lower) in Mustang II suspensions. At times you may need to add a washer under the castle nut so that the cotter pin is engaged fully into the nut. Beyond that I can't think of any other spacer that could be needed.

These balljoints have a stud with a 7 degree taper (1.5” of taper per foot). The minor diameter varies somewhat from one example to the next, but is always near 0.5”. If you wish to determine the suitability of this balljoint for a given application I have found the easiest method to be simply going to the local auto parts store and asking them for the equivalent of a Moog K772. Or you could of course ask for the balljoint that fits the following applications: · Chrysler 300 1962-71 Cordoba 1975-83 Fifth Avenue 1983-89 Imperial 1981-83 Lebaron 1977-81 New Yorker 1963-82 Newport 1961-81 Windsor 1958-61 · Dodge 330 1963-64 440 1963-64 880 1963-64 A100 1964 Aspen 1976-80 Challenger 1970-74 Charger 1966-78 Having the part in your hand makes it MUCH easier to gauge its suitability and all the myriad additional measurements you may need. Please consider this information and let us know if we can be of further assistance.
