The cons are the added expense of rear shocks over just the coilovers, but honestly, that's pretty much it. Pros: while most of the sloppy handling of a bone-stock F150 is caused by the front struts, the stock rear shocks cause a lot of the bounciness that you feel going over bumps and ruts, as they don't tend to settle if the bed's unloaded after an impact. The Fox 2.0 rear shocks alleviate that problem and keep the rear end of your truck much more settled and controlled.
