I installed Bilsteins on the front and rear, I set the front at 2.1 and after it was done I had a level truck. I installed a Bakflip fiber max and now have about a 1/2 reverse rake. So I need to raise the rear about an inch or so to get it to level back out. If I leave 5psi in my TLC it sets level. But I have a slow leak and I cant find it right now and its to cold to let the lines reset to find the slow leak. Thanks for the input.
