Quick Overview
For maximum ride height, install the Fabtech 8" radius arm lift kit on your F250 and F350 Super Duty. This lift kit features Fabtech's massive Dirt Logic 4.0 Coilover conversion. Expect outstanding damping capacity while offroading and a quality ride on the pavement. The Coilover simply bolts in place of the factory coil spring without requiring the removal of the coil spring bucket. To allow for full compression travel when running oversized tires, the 4" diameter aluminum remote reservoir mounts above the Coilover. We think you'll agree the Dirt Logic 4.0 Coilover is the biggest and baddest on the market for the Ford Super Duty! The Fabtech 8" patented Radius Arm lift kit levels and substantially lifts the truck. The radius arms feature a full tubular structure strengthened by dimple die side plates, with an adjustable alignment cam at the axle to allow caster adjustment. Also included is an offset, extended length track bar that is adjustable to address the hyper-sensitive steering box. This exclusive feature repositions the track bar to be closer to neutral with the factory drag link resulting in reduced bump steer and tire shake. The track bar is 4" longer than stock and attaches to the frame with a 1/4" thick frame bracket offset to the driver side with a support brace to eliminate deflection allowing a 15.5 wide tire on 5" backspace wheel to turn full lock without interference.
