You can save a pretty penny by avoiding the Delta-Joints. I have them and honestly I'm not sure it's worth the extra $$$ over JBA's. I've helped install both, and I wish I had gone with JBA's from the start.
And as far as the trac-bar is concerned, I'd go with
Sonroan steel.
You really can't go wrong with either shock. They both need rebuilding, both cost a ton, both have their fanboys.
You'll be able to make a better, more informed decision by visiting either Filthy Motorsports or Accutune Offroad and reading and watching their material on each.
