Which ball joints?
The Synergy's are proven. The Dyna's are better, and rebuildable, but at twice the cost. The Synergy are a fair price and I have not known of anyone yet who has had to replace a set of Synergy ball joints.
If you have the $$ and want to do it right the first time, go with the Synergy HDs… I ran them in my previous jeep and loved them. They are a bit of a bitch to install and the boots are flimsy, but well worth the time….
If I am not mistaken, I believe the Synergy HDs are also rebuildable...
