Just put these on my 2013 4x4 today.
Fronts set at 1.75"
On the rear im using 1" blocks with the stock 4 leaf springs.
Im realy happy with the way it looks.
One day I might go bigger once time comes to buy new tires but thats a long ways away.
The ride feels slightly stiffer in the front end , but not to bad .
Next I have to buy some steps or sliders.
