This is why I am thankful I had it done at a shop. They charged me $110 labor to install the front spacers and rear blocks plus alignment. They literally did front and rear in 1 hour (not counting alignment). I timed them. I didn't get to watch them install. But the mechanic said he has done it so many times it was easy for him. A 2" AS allowed me to fit 295 70 18 Trail Grapplers with zero rubbing.

 

Also, noticed that the spring is broke at the lower perch. Must have been this way a while.. has rust on both exposed ends. Simple job now getting expensive...

 

check with some of the forum members that put on Rancho Quick Lift, should have some springs laying around that will sell cheap or give you them.
