My plan is run mudflaps in the rear only, as it is not required in the front. The lowest point of my frame will remain less than 26" off the ground. I will maintain less than 4" between the frame and the floor. My front bumper should be less than 31 inches of the ground. I will have a makeshift rear bumper mounted under my spare tire carrier. I consider coilovers to be heavy duty shocks for the drivetrain I am running. I am going to run hydro assist.
