I just bought a 2014 Ram Big Horn 1500. The front is exactly 2 1/2" lower than the rear. I want to raise the front and not sure which way to go. Need some advice! Should I use Hellbent spacers or Bilstein 5100 shocks? If I use the spacer , are they a true 2" or 2 1/2" lift? What size should I use? I intend to keep the stock 20" tires.
