Interesting. Where are you ordering them from? Can you rent the tools to change the ball joint from the auto parts store?

O'Reilly auto parts has them for $134 plus $25 discount on $100+ orders so I might do that and make two separate orders.


A large c-clamp and some sockets will do the same job as probably $100 worth of specialty tools. You can also rent bushing press tools as well.

I've seen a few offset ball joint options like this, and while I'm sure they reduce stress on the ball joints themselves, they do lack the other benefits of JBA UCAs.

The JBA UCAs are thicker and feature a ball joint with 90 degrees of motion. The ball joints are also easily serviceable and replaceable without a ball joint press. The longer arms also allow a much larger range of motion before hitting the strut than the stock UCAs do, and make sure that the ball joint is angled correctly for a lifted suspension. For off roading, these features mean the JBA UCA is much less of a failure point, and in an emergency a ball joint can be swapped out quickly.

With that being said, for a street lift I do think these offset ball joints are a great option without breaking the bank. They should help with alignment problems for a lifted XK, and they do appear to be designed stronger than the stock options.

Ive seen these around and considered using them for awhile. I have MOOG problem solvers in the stock arms atm and that works ok, though some extra adjustability would be better.

I tried getting my stock ball joints off with a ball joint press like the one shown in the OP video and ended up giving up and asking a nearby shop to do it for me. If you dont have a large freestanding press I wouldn't recommend it...

I look forward to hearing about your experience.
