We're actually huge fans of Zone's suspension lift kits, and we've used them with great levels of success on several of our other project trucks over the years. Zone's lifts come with high-strength, high-quality components that fit extremely well. Combine that with Zone's fairly low price, and you get a pretty awesome lift system that lets you clear big 35" tires without breaking your bank. Granted, the downsides of a lower-priced lift kit is that its actual suspension hardware really isn't suited for the kind of off-road performance applications that we generally have in store for our trucks. The front suspension lift is achieved through the use of strut spacers that install on top of the factory front struts. Rear suspension performance is provided by Zone Nitro rear shocks, which are pretty basic general-purpose shocks that are slight improvements over stock. The trails we went on were pretty rough, semi-maintained trails that conned some of the larger fire roads by the base of the San Francisco Peaks. The roads were deeply rutted and had a mix of deep snow, mud, ice, and puddles throughout their runs. The Zone System did surprisingly well. The factory struts and Zone Nitros were able to absorb and perform very well on the trails up to about 30 mph. However, you definitely feel the extremely violent impacts up in the cab. While the system didn't hold a candle to our 2015 F150 5.0L's BDS 4" Coilover Suspension Lift Kit, it was more than good enough to handle those pretty tough forest roads without much fuss, and its tire clearance gave us the room for 35" Nitto Trail Grapplers that helped us burn through deeper snow drifts with ease. Overall, the Zone Kit is a good general-purpose lift that will serve you well in light-duty off-road situations, but extremely high-speed driving should be left to dedicated coilover lift kits.
