I would stick with factory ball joints, They have the best quality that I have seen.
The joints marked 555 are made by the oe supplier and are good as well.


1987 trooper LS.'94 3.2, SAS,35's , lots of dents and rust. Now, improved, with more dents.
1995 trooper LS. Wife won't let me improve this one.
1996 trooper. I'll need something to modify when the '87 finally rusts away.
