The Fabtech Dirt Logic 4.0 coilover conversion for 2011–2016 Ford F-250/F-350 4WD converts the factory coil spring bucket to a 4-inch coilover solution for faster installation and upgraded damping. Dirt Logic units use stainless-steel bodies and NitroSteel piston rods for corrosion resistance, providing a durable coilover option that bolts in place without removing the coil spring bucket for a straightforward suspension upgrade.
