Has anyone tried using both methods to lift the front of their truck? The c style block under the shock and the spacer above the strut? I don't want to waste the money on both if it won't work. Thanks in advance!

I am putting HID's in my high, low, and fogs with a relay so when I turn my high beams on my fogs stay on as well. Do I need the anti flicker compactors and wiring harness for all 3 sets? Or is it just for the low beam set? Also I'm going with Kensun because I've had a set of them on every vehicle I've owned and never had a single problem out of them. Thanks in advance.
