LOL!! I suppose you would consider a brand new Teraflex axle to be better than a used ProRock regardless of how good of condition it is in.
The currie tie rod is physically bigger, physically stronger and has physically larger and stronger joints and it is easier to adjust due to its factory like design. These are FACTS that if you took the time to look up and or compare for yourself, you would know that I'm right. That being said, where's your proof as to how the synergy tie rod is "better"?
LOL!! Oh please, local shops recommended the synergy tie rid and that what makes it better? You'll forgive me but shops recommend what they have in stock and/or on what they can make the most profit on. Just because something costs more doesn't mean it makes them more money.
To be clear, I never said that the synergy tie-rid was "bad", just that the currie one is "the best" you can buy. And, so that it isn't missed, I don't even like the guys at currie and I would never recommend other products that they make like their axles for instance. Unlike the synergy fanboy you seem to be, I just call it like it is - you of course can take it or leave it. It's no sweat off my back
