Not sure on the Stangs with a live axel, but I used them in my GTO with irs. Helped immensely. The gto has a very bad wheel hop problem. Used to keep diff psi in each side to help the harmonics. Worked very well. I have not experienced hop in my 14 yet. Had gt500 lcas for the first 1000 miles, and Steeda now for the last 5000.
