Most Popular Rear Pair for 2018 GMC Sierra 2500

Very easy to assemble and install. Follow the steps in the instructions and all will be ok. If you purchase the screen with it, read those instructions before assembling the mud flap system. There is a lot of overlapping steps that might help in your assembly. Great product. A+++++

Simple to put together. Arrived quickly. They have accessories that you can add. Bought them to use on our Alaska trip.

Good so far, but just put them on. Don't know if the attachment hardware will hold in the long term yet. Delivery was very quick from etrailer.

Bought these along with the set for the front. The goal is to cut down on road spray, grim build up, and stones kicking up into trailers. These look really great and match the factory trim package that has trim on the wheel wells. They look really good, but these were a little more difficult to install due to the trim that I have on my wheel wells with the All Terrain package. I was able to make them work and they look great, but it was not as easy as turn and tighten.

It fits my needs perfectly

Great quality and fast delivery

Works great, best to have a way to keep your reducer or you stable is best Does not give you torque spec on the mount to hitch but make sure that is tight, had it come loose and scratch my bumper but that’s installers fault

We bought these in preparation for our four-month long trip to Alaska in 2024. Wish I had bought these when we bought our Airstream, since it got beat up a bit prior to using the Rock Tamers. Highly recommend these!

Seond set purchased this year, good quality, design works well with dirt and avoiding rock chips.

The product did what I wanted it to do. It kept stones and debris from hitting the camper. However, when you cut the flap to a height that is compatible to a good running height ( 4" above the road) the flap drags going in and out of parking lots. On one trip it drug so often the flap had a tear at the mounting bracket. I sent an email asking if I could purchase just the flap but I got no response. So I improvised and put another metal bracket joining both sections of the flap.

Very easy to install and looks great. I shimmed my receiver hitch to ensure it did not wobbel. Protects my fifth wheel from gravel and road debris.

The rockstar mudflap is pretty much bulletproof, I’m very happy with its performance and durability.

I have not had a chance to use the flaps yet but, upon assembling them, they are certainly heavy duty. Construction seems very good with aluminum and stainless steel bolts. One of the trim pieces arrived with scratches on it. After writing customer service, a new trim piece was mailed to me. Definitely a plus doing business with etrailer!

Fairly easy to install, instructions do call out a specific torque, so a torque wrench is a good idea. The flaps are heavy and should last a long time. The 2" etrailer shows from the bumper to the drop on the ball mount should probably be 2-1/4" The only con I can find, the height is not easily adjustable, you have to remove and redrill the flaps. I set mine at 5" and need to raise them to 7". They drag when I pull into the driveway.

The flap itself is excellent, having a receiver mounted one very convenient. The issue I had was the single bolt used to snug up the entire setup. The previous units had two one one each side. To Roadmaster’s credit they were willing to accept my hitch mount and replaced with a two bolt version which solved the issue completely.

Okay there are only a couple small things that I have to grump about. First is that the mud flaps come rolled up and it is very hard to get them to lay flat now as you can see in the picture. Second there is no center flap included for total protection from debris flying from under the vehicle. Last thing is there should be a bar included for the bottom of the flaps to keep them laying flat all the time. On the other hand...Etrailer.com really rocks!!! This is the first time that I have every used them and I will be using them again for sure. You are always being updated on the progress of your order. You order ships out right away and I had my order in a couple days. The price of this product from Etrailer.com was the best on the net that I could find. Oh yeah, and the fact that I got this item with free shipping is a total plus to me. Again I would recommend this site to anyone because they are good.
