I would buy this product again
The threads are not the same as the threads on the control arms they are supposed to thread into. The helpful speedway staff said just press them in and it worked just fine.

Screw type ball joints
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

These ball joints are the ones that are used in the Speedway tubular lower A-arms for Mustang 2, Pinto front suspension systems. They work very well.

I'm looking to modify my control arms to use this Ball Joint. If I need to go to an extended length would the Speedway PN# 91721134 Ball Joint interchange? would the taper still be .73 at large end and .62 at small end? Thanks! Steve
