Most of ADD's bumpers are pretty similar to the OEM in weight. Even if it was, lets say, an extra 90lb...think if it as having a teenager in the front seat. Even if you added a car full of people, you don't typically notice. So adding the weight of a heavy teenager to the front of your truck is little to no difference.How much weight are these adding. Are you seeing worse mpgs, sag front or back or are they about the same weight as stock. I assume heavier and yes to all the above.
