Fairly easy installation. Just make sure you are using the right bolt and washer found in the installation guide. Thick heavy duty flexible rubber. Installed front and rear on a 2025 super duty.
Great product. Easy to install, but a bit more complicated and involved than a set of fronts. I had the wheels removed as I was doing a tire rotation. Made it a lot simpler. Hardest part was drilling the plastic fender liner to accommodate the new mounting screws. The small 1/4" headed screws that replace the OEM 7mm were problematic. My 1/4" socket like to slip on them. I got them tightened up anyway. Once everything was in place. they needed little adjustment to set them plumb. All in all, a great product.
Installation is really straight forward. I did not remove the wheels for this install. I simply turned them inward at the rear. I have 35" tires, so I installed the aluminum bracket all the way rearward and bent it back slightly at the right angle. This was to ensure the tread does not rub on the inner edge of the mudguard. They needed very little adjustment to set them plumb. The two 1/4" headed screws that go into the existing body mounting holes should have a slightly larger head on them. I found my 1/4" socket wanting to slip on them as I tightened. The OEM 7mm were perfect. All in all, a very good product.
I am only going to write one review to include the flaps and support hardware. I previously had a set on a 2018 Ram 3500 Dually and installed them easily myself (with some effort - I am 77 years old). I recently purchased a 2024 Ram 3500 Dually and immediately ordered another set. The order site did not show a 2024 but I figured the 2023 version would fit. Some of the holes did not align up but, I made some adjustments and still got them on. The grooves in the tub are a little different but, all turned out good. The exhaust pipe hangs down a little more than the 2018 and there are a couple trim pieces that cover the inside corners.
Short and sweet Very easy to install - high quality fiberglass upper body matches the original caps - Lower end in thick rubber composite, name GMC appears to be stainless. Highly recommend Mike
