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).

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.

Why it's not fit for my 2017 gt? and body shops can not do it even need cut a part of my rear bumper

HarryD

  • The Roush Rear Valance is designed to fit with the 15-17 GT, ecoboost, and V6 packages all in premium trim levels as this is pre-drilled for the backup sensors, which are not included, or on ,the standard package mustang gt, v6, and ecoboost.

Other than the Roush or Corsa axle backs what other axle backs can be used with this rear valance? Could I use any axle back as long as I use a quad tip exhaust tip?

aueagle1

  • Since this valance is mainly designed for use with the Roush axle-back exhaust systems, any other exhaust systems will have to meet the same measurements as the Roush exhausts to fit correctly.

    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

    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.

    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.
