Basically you can only lift the front end around 3". I'm not sure how much the lift the springs provide, if you install the springs with the 5100s at the lowest setting the only lift you will gain is from the springs. You can raise the setting on the 5100s in combination with the lift springs to achieve the desired height. Once you get up to a total lift in the 2.5 a 3" range your front suspension is maxed out.
