Im going to be getting a 2 1/2 suspension lift and the kit comes with anti invert shackles. My question is should I swap those out and go ahead and put in 1"or2" over stock shackles on for a little more lift? Does it make that much more diff either way. Will the handleing or ride be any different between the two? Right now I do light offroading but am planning on moving out west with hopes of doing it more often. I have an FJ62. For now I will be riding with 31" but after they wear out will go to 33" tires. Any thoughts ???
