Unfortunately, Fox does not currently offer full-length Fox 2.0s for F150s with 6" lift kits. You could, feasibly use the coilovers in this kit in conjunction with the strut spacers included with most lift kits and get a good ride. However, the shocks in this package are not long enough to work with 6" lifts, and you would need BDS's Fox 2.0 Shocks for 6" lifts.
