Does anyone know if the V8 WJ springs give lift if installed in a I6 WJ, like the ZJ guys do? A pair from the JY springs with your 2" spacers may be a cheaper way to go. Just throwin it out there.

 

A stock V8 ZJ spring shouldnt give any lift to an I6 unless it was up country suspension. It will just offer a firmer ride. Same for the WJ. But if you find some low mileage V8 springs and swap them in from some high mileage I6 springs you may be onto something due them being more stout.

Now the front to rear coil swap for the ZJ is another story... Sadly doesnt work for WJs though.

As for the OP... lifting your WJ to fit the tires, i would go with the IRO 3" lift. I believe it comes with everything you need to be ready to roll. When i need new shocks, Im dropping the 2" BB and going to that.
