Fabtech's Dirt Logic 4.0 coilover conversion is a front coilover upgrade for 2011–2016 Ford Super Duty trucks (F-250 through F-550) designed to replace stock coil spring buckets with gusseted 1-3/4" tubing to accept Dirt Logic 4.0 coilovers. The conversion increases travel and progressive dampening capacity for improved on- and off-road ride quality. Hydraulic bump stops are available as an option, and the system is compatible with both radius arm and 4-link layouts.
