Enthusiasts very often hear about the quad shock flip on Fox Body’s and other Mustang models but rarely do they get all the info about what this means and how exactly to perform the process. We at LMR have made this specific article addressing these issues and how we can make this process quick and easy!
Ford has to meet a certain set of Noise, Vibration, and Handling requirements on their passenger vehicles. When Fox Mustangs were built, there was a certain level of compliance in the suspension bushings that was necessary to make the ride bearable for the user. With this compliance, the rear axle could move or rotate a small amount when under load. With harder acceleration, the axle would move forward and backwards on each side which created the popular term known as “wheel hop”. The creation of the quad shocks was Ford’s way to slow the movements down with a pair of horizontal dampeners as well as create more clearance for larger tires.
Now you may be asking yourself "why would I need to flip my quad shocks?". Fox Body owners flip their quad shocks in order to get wider wheel and tires to fit the rear of their vehicle. The quad shock has a large diameter on the cylinder side and a thinner diameter on the shaft. By flipping your quad shock, you place the thinner shaft side in the area where the tire would rub the cylinder in order to gain a little more clearance.
