There shouldn't be any issues if that's what your worried about. The HD springs supply the same amount of lift as the budget boost I believe so adding the spacer to it increases your lift even more. Just be sure to flex it out with a jack at home and check all the angles and everything but if you leave you sway bar connected and or have stock length shocks on you should be fine. Keep in mind though with stock length shocks and adding the amount of lift your going to your limiting your down travel by a lot.
