Falcon has not confirmed this kit to fit the 2021 F150s. While many components will bolt up, Ford actually did change the UCAs and the suspension geometry on the 2021 F150s, which causes some issues. Even with Roush's 2.0 coilovers, Roush requires you to lower the ride height setting for fitment on the 2021 F150s, and Fox themselves are likely coming out with an entirely new part number for the 2021 F150s. As far as setups that would also work, frankly, just about any aftermarket set of shocks and struts/coilovers would be an improvement over stock. Depending on what you're towing, you may want to add some sort of rear lift or rear load support on top of any suspension setup you choose (some of which, the Falcons can't handle). Your best bet would be to call us directly at 623-434-5277 or email us at [email protected].
