I'm going to be doing a project over the holidays to convert from the stock OEM style struts in the front of my 2008 4x4 Explorer to Fox coilover shocks. The goal is to get a mild amount of lift (around 2.5") and increase the front suspension travel. In stock form, the 4th Gen OEM front suspension with the OEM type struts has a bit over 4" of wheel travel. I will be using Fox 2.0 Emulsion coilovers with 5" of travel. If my math is right, this should result in about 8.5" of wheel travel available (will probably be slightly less than that since I'll need to run limit straps) I am going to do everything possible to make this a bolt on installation as far as the way the shock brackets are designed. So far, I've just gotten the shocks and springs (10" 750lb spring rate eibach coils) and extended lower shock eyelets. I think it would be possible to run a 6.5" travel shock, but the front diff might have to be dropped down a bit with brackets in order to reduce the stress on the CV axles at full droop. So for now, I'm staying with a 5" travel shock. More to come.
