Product Description

Add a different look to the rear of your 2013-2014 Mustang with a Boss 302 rear valance/diffuser. This is the same Rear Diffuser/Valance that is factory equipment on the 2013 Mustang Boss 302 & California Special. It features a black textured finish & is an OEM Ford part. This rear lower valance/diffuser is an upgrade for 2013 Mustang GT and V6. Installation of this kit on your 2013 Mustang GT will require you to cut off the lower section of your bumper cover & cut new slits to retain the lower valance. Luckily Ford saw fit to mark EXACTLY where you need to cut on the back side of the bumper! Plus, all needed hardware & instructions are included.

Start to finish, this install will take you a couple of hours & the only specialty tool needed is an air powered body saw (available @ Harbor Freight, Sears, etc.).

This diffuser/valance will greatly improve the rear appearance of your 2013 Mustang GT or 2013 Mustang V6!

  Simply a Must Have!

Image uploaded by Jake M. I bought this around 2 weeks ago, ordered on Sunday, arrived on Wednesday, installed on Friday. This OEM valance completely changes the rear end of the 13 and 14 Mustang and in my opinion should have came stock from the factory. It makes the rear look much more aggressive.
Only negative is that it requires some cutting to install properly, so take your time!!! Otherwise, I'm very happy with this rear valance.

Yes, I would recommend this item to a friend!

Image uploaded by kaden g. I bought this couple weeks ago, got around to a install. The install is MUCH easier once removing the bumper I found out. There are pre-cut marks on the inside for anyone wanting to do this but scared to mess it up like I was, remove the rear bumper and cut along the already laid down template. I wouldn't go back. Absolutely love how much aggression it added to the back of my car! Couldn't be happier with the product, next day shipping, and outcome. Great job Latemodel Restoration!

This makes the car look so much better. Aggresive but looks like stock. You will need to remove the rear bumper on the car to do the installation. Once you remove the bumper you will notice that the factory bumper has the exact lines and tabs that need to be cut. Follow the lines on what to cut and cut the marked tabs and the installation will go smooth. The necessary hardware is included .
Great look !!!!!! Definetly recommend the boss 302 rear duffuser !!!!
