The two major differences bewteen our Fox shock and the other brands is Quality Construction and Tuning. No one else on the market specifically valves shocks for our Mopars. They all have a ballpark, or in the case of QA-1 or Viking, they just have a shock that covers a wide range and it is up to you to find the tuning. With our adjustable shocks the shock is tuned to be slightly softer than our non-adjustable in the softest setting, and gets stiffer from there. It's something that has to be driven on to be truly believed. Ask anyone running our shocks compared to what ever they were running before and see what they say.
