Stock is 100 % fine, I just wanted a factory rake or even a bit more level. Any lift added will not affect anything, the coil rate of the springs affects stiffness and ride quality. Bumper will not affect the alignment on a solid axle rig.
I would like to know how any portion of the steering would come close to the frame even if it was in full compression it should be clear of all things.
I just drilled a hole and bolted the outer edge of the inner fender to the flange of the bumper, There are actually a specific snow plow package spring that is heavier than the stndard suspension, there are actually many different part #'s for the front springs, the snow plow spring part # ends with 988AA.
I paid 800 off e-bay for the one on my 02 with free shipping and I bought the ones for my 05 and 2010 1500 for 1100 each through a local dealer.
