      • Improves Handling Performance
      • Reduces Suspension Flex
      • Tubular Steel Construction
      • Black Textured Powdercoat Finish
      • Fits All 1979-2004 Mustangs


      Improves Handling Performance. Improve your Mustang's handling performance by reinforcing your rear shock towers with a SR Performance rear shock tower brace. A SR rear shock tower brace will stiffen your Mustang's chassis to reduce suspension flex and improve traction for impressive corner carving handling.

      Superior Construction. The SR Performance Mustang Rear Shock Tower Brace is made from heavy duty tubular steel to keep your rear end from flexing under g-load and is completed in a textured black powder coated finish for aggressive good looks and long lasting corrosion resistance.

      Application. The SR Performance Rear Shock Tower Brace is designed to fit all 1979 to 2004 Mustangs, including the LX, V6, GT, Bullitt, Mach 1, and SVT Cobra models. Technical Notes. Some modifications and welding may be required for installation. 1979-1993 hatch back will require light trimming of factory inner quarter panel sight plugs over rear shocks. All other models will require trimming of factory inner trunk liner.

        Doesn't fit?

        I tried to throw this mod in along with my sway bar's on a very hot day and found myself standing in the trunk sweat pouring down my face and into my eyes and I had a meet to make it to. Problem was that the added thickness won't let my nut's get on the shocks, this isn't due to this product in particular rather the amount of thread on my koni oranges. I'm sure I'll get it to fit when I'm not in a rush

        Works great, very good bang for your buck. Had trouble installing because of the way my shocks were set up but in the long run it fits great.

        Suspension Add-On

        I wanted to add more rigidity to my Fox. I installed this in about 20 minutes and the car definitely felt stiffer in addition to the other suspension components I installed. For the price it's worth the extra peace of mind.

        Should not have waited.

        I wondered if something this simple could really make a difference in driveability. Long story short I waited far too long to buy and install this shock tower brace. This, as well as the front strut tower brace, have made my car feel 100 different in turns and uneven roads. Mustang's are not known for outstanding handling, but both the front and rear braces definitely take a big step in the right direction. Recommended to anyone on the fences like I was.

      My cars shocks/struts are not that old but having a passenger and big grocery hall and it floats all over the road and bottoms out easily. Will this and the front brace help or do I need a pricier setup? Thanks!

      • The SR Performance Rear Shock Tower Brace and SR Performance Front Strut Tower Brace will reduce flex from side to side, but will have no effect on the vehicle bottoming out. This is most likely caused by failing or failed shocks/struts, or spring rates that are too low (soft) or too low of a ride height.
