    Review & Installation Video

    Formidable Roush Styling. Now you can add a formidable new appearance to your S550 Mustang with a Roush Performance R7 Lower Rear Valance. Designed using the original manufacturer CAD data for a perfect fit, this is the same exact rear valance found on the new special edition Roush Mustangs.

    Quality Construction. Made in the USA at Roush's own plastics manufacturing facility from OEM quality high pressure injection molded high-strength thermal plastic olefin (TPO) for it's long lasting durability, this rear valance features a stippled grained texture for an OEM look and to increase longevity against rock impacts from daily driving.

    Pre-Drilled for Backup Sensors. This Roush Performance Rear Valance is available already pre-drilled to simplify the installation of your stock back-up sensors. If your Mustang is not factory equipped with back-up sensors please use Roush part# 421894.

    Required Upgrade. For proper installation of this Rear Valance you will be required to upgrade to a Roush Quad tipped exhaust system. GT models will need Roush Part# 421920 or 421921, EcoBoost models will need Roush Part# 421922 or 421923.

    Application. This Roush Performance Rear Valance is specifically designed to fit 2015-2017 GT and EcoBoost Mustangs equipped with the factory Premium Chassis Packages only (Trim Levels: 200A/201A/400A/401A).

    5 Top Rated Questions

    What is different about the Premium Pkg GT vs the Non Premium GT regarding the rear bumper ? My car is not a Premium Pkg GT and I do not have the Trim levels listed on the AM site, so the way I read it, I will not be able to purchase the Roush Rear Valance at all. Correct ? I really was hoping to someday get the Roush Quad tip exhaust to go with it but I guess not. Please let me know if you have any ideas on how to make this work with this Valance or another vendor's Valance so that I could do the Quad tip Roush exhaust. Any ideas would be appreciated.

    • The main difference between a GT/EcoBoost Premium vs a GT/EcoBoost Non-Premium exterior wise is the rear bumper. A Premium Mustang features a "2-Piece" bumper that features a black rear valance panel (Ford part# FR3Z-17F828-AA) that sits between the lower diffuser and the main bumper. The Non-Premium bumper is a 1-Piece Bumper that does not feature that valance piece. Instead of trying to modify a Non-Premium Bumper and the valance to make it work - which there is no type of instructions available, since Roush designed their valance for the Premium Bumper - it would be easier to remove the Non-Premium Bumper and upgrade to the Premium Bumper.

    I have a 17 GT premium package with a Corsa sport exhaust. I would like to get the Corsa quad tips, will the Roush rear valance work with this?

    • The Roush Rear Valance is specifically designed to work with the Roush Quad Tip Passive Axle-Back Exhaust, item # 388835, (https://www.americanmuscle.com/roush-quad-tip-axleback-2015gt.html) and the Roush Quad Tip Passive Axle-Back Exhaust, item # 388836, (https://www.americanmuscle.com/roush-quad-tip-axleback-2015eco.html). This Valance is not designed to work with the Corsa Exhaust.

    I wanted to know if I am aloud to get separate parts? Cause my driver side side part broke from the Roush rear valance and I won’t be able to fix it. Is there anyway for me to get that part?

    • At this time, we do not offer individual components for the Roush Rear Valance. We would recommend contacting Roush directly, as they may be able to supply you with individual components.

      Disappointed install

      I feel this could have been designed much better. 13 little screws that hold it on and then a strip of tape. My biggest issue was the supplied template does not fit properly. You will defiantly have some screws that to not line up. I would say about 7 of the 13 actually were on target. And if you have parking sensors, the cut outs on the template are not big enough. The end result may look okay but I feel they could have made this much better. For me, just to add quad tips, knowing what I know now, I would have not done this and simply left it alone and installed a normal exhaust set up. And some say 3 hours to install.... not in my case. I took my time, and walked away when I would get fruastrated. I have yet to install the exhaust to see about fotment issues with the tips that some have reported.

      Great look!

      Not the best instructions, but it gets the job done. Also very nerve racking to cut into the bumper cover. It took me all day to get this to fit right.

      Very disappointed about this valance

      Received this valance with much anticipation. It did not come with any directions other than return directions (that should have been a red flag) and a website for placement directions. The paper cut-out that came with the valance was not cut very well to size even though I cut perfectly along the lines. Did not match up to my Corsa exhaust that American Muscle recommended would be a perfect match for this exhaust during my purchase. Exhaust is great but because the Corsa setup has 4.5" tips, rather than 4" tips, the inner muffler tips are touching the new valance and melting it. Very disappointed in the entire process from both Roush and AM. I'm going to go with a GT350 rear bumper and valance which I should have done from the beginning.

      Make sure you order the correct one!!!

      As other reviews as indicated, it is a bit more work than perceived, but completely manageable to do without a shop. However, please learn from my mistake! When ordering it will ask you if you have back up sensors or not. I went and took a look and while I did notice I have them, they were installed several inches above the existing rear valance, and not in it. Assuming Ford made other models that had the back up sensors located IN the valance...I indicated I did not have them so I would not have 4 holes in my new valance unused. So after dismantling the back end of my car, and having already cut up my bumper to fit the new one...I then discovered that the new Valance is taller, and installs OVER the back up sensors on the actual bumper. Being my only vehicle, single, needing to get to work the next day, and with my old one not able to go back on due to all the cutting...I had no choice but to install it over the sensors. They now toss up an error message on my screen every time I back up, and of course not functioning. With that said I absolutely love the product itself...looks great and sounds even better! It just stinks that having already bought it once, now I have no choice but to save up another $250 bucks to order the correct one, and spend another half day making the swap. So please take heed! If you have backup sensors, (even if they are not located on the rear valance) get the one with the holes for them! Note to AM: A loyal customer for years now modding two mustangs, and have nothing but great things to say, you guys rock! But please do others a favor and make a note about the back-up sensors on the product page...that it WILL cover the existing even if they are NOT located in the Valance..but above it! My bad for over thinking I guess, and i'm sure some others maybe laughing over this :-), but would hate to see someone else make the same mistake! Once my piggy bank is full again...I'll be placing my order for the correct one.

      A lot harder that what it looks

      Don't be fooled... This is not a simple installation at all. The instructions say 3 hours, but that's completely false it's more like 6 7 hour job. Everything has to come off the whole bumper the tail lights the sub in the trunk. There us also a lot of cutting required that you have to do which I was not clear about. This needs a professional to do it because this is a lot harder than a simple installation

      complicated installation not for the novice

      Instructions said 3 hours for the novice, they were wrong. I took it to a very experienced and quality body shop and it took them about 6 hours to properly install. Otherwise it looks great.
