Fabtech and Rough Country both released their “4” inch lift kits specifically for the AT4 and trailboss. “4” because it lifts it 4, but it sits like a 6 inch. Fabtech said they’re not going to release just a level, rough country said later in the year... not sure what ready lift will provide. The 6 inch lift isn’t a option for me. So I guess I keep waiting.
