I have a 2.5 inch rustys springs with 1 inch tera flex spacers upfront. why do companies say the rear sway bar links will not worrkon the rubicon fronts? I bought black diamonds and had them on for a couple months but thought they were too long. swapped them for the stock rears (put JKS on the rear) and seem to be working fine! Is there something I am missing? both rear and front seems to have the same bushings just different lengths!

 

Anyone know the reason? Or is this not true?

 

There are several lifts from good companies that have you swap the rear to the front and only include replacement links for the rear. My terraflex 2.5" coil lift is like this.

So I don't see any problem if your lift is in the approx 2-3" range...

 

the factory rear links should be fine on the front up to about 3" of total lift. a lift that is too short would cause the factory rears not to work, also.
