      Review & Installation Video

      Hey guys, Stephanie with here, checking out a fast and sure fire way to stiffen up the suspension of your 2005 to 2014 Mustang with this SR Performance rear shock tower brace. SR Performance has a wide selection of performance and suspension components for your Mustang, with prices that are budget friendly and price points that are consistently lower than competitors, all while offering equal or greater quality products. If you'd like to check out more from SR Performance for your Mustang, you can always head back to the website and check out SR Performance under the featured brand section of the home page. This SR Performance rear shock tower brace has a tubular design that does an excellent job of reducing suspension flex and body roll, without creating a harsh feeling in your suspension. It reinforces the rear shock towers and keeps the car from flexing, and it also improves traction by helping to plant the rear tires on the road. This brace also provides balance to a front strut tower brace. The brace is also constructed from tubular steel, and it's powder coated black, so it looks great tucked into the trunk of your Mustang. If you'd like to see some more of this shock tower brace, you can check out some customer submitted images of it installed on customer cars on the product page. While you're there you can read up on some customer reviews of the product as well. Keep in mind, while the shock tower brace does a great job on its own, it does pair really well with other suspension upgrades like a strut tower brace, which I would recommend purchasing with this, or a set of lowering springs and some sway bars. It does a great job of tying all these mods together. Installing this brace should take you about an hour, and you might need to trim just a little of the trunk liner for the install. You guys should also note that this brace will not work with your 'Stang if you have a Shaker 1000 system. If you guys have any questions about the shock tower brace, or the install itself, you can always reach out to one of our many Mustang experts by phone or by email, and they'd be more than happy to help you out. If you're looking for a quick and budget friendly way to tighten up your Mustang's handling, then you should check out one of SR Performance's black shock tower braces for 2005 to 2014 Mustangs, available right here at

        Good product looks solid, shipping was fast but didn't come with all the bolts to put the middle plate on. I will buy from American Muscle again but I hope I can get all required parts next time.

        Game Changer!

        Bought this with the front brace, both of them together make for a very pleasant handling experience. Took me a bit to put it on simply because I had to figure out how to get the bolts off without the entire strut spinning with them with my basic wrench set.
