How Fox’s Live Valve Evolved From a Failed Project to a Game-Changing Technology 11 Mar 2021, 12:36 UTC · by 12 photos The highlight of the recently revealed 2021 Ford F-150 Raptor is the redesigned suspension system that features Fox performance shocks. They use the latest version of the company’s innovative Live Valve technology, which has been providing intelligent, electronically controlled damping to high-performance off-road vehicles and mountain bikes for years. To maximize comfort, handling, and bottom-out resistance, Fox shocks fitted with this technology use a fast, semi-active valve and a patented damping architecture. They can promptly adapt to any terrain by adjusting compression damping according to sensor feedback and driver or rider input.
