Thanks for those that clarified the "frames" were not necessary on a Dodge. I installed without removing the inner liners because my mud flaps have a lot of fasteners and it was too much work. I agree it would be easier without the fender liners. What was a huge hassle was the length of the bolts on the stable loads. They are 3 times longer than necessary and make it impossible to get them into the frame holes even after pumping my air bags to 90 psi to lift the truck. I ended up cutting 1 1/4 inches of thread off and still was not enough. Should have whacked at least 1 1/2 or more. After hacking the threads, it is a challenge getting the nuts on. This whole process could have been simple if the threads were shorter. If I had a jack and raised the truck it might have been easier but I'm at a campsite so tools are at a minimum. Pain in the as&$
