Application and installation
Use only on the listed 2012 F250 4WD 6.7L diesel configuration without the factory rear overload leaf and without a factory rear sway bar. This listing excludes vehicles fitted with the FTS52002 dual-shock conversion.
Manufacturer wheel guidance, with minor trimming: 355/65R18 tires on 18x9.5 wheels with 4.75-inch backspacing, or 37/13.50R20 tires on 20x10 wheels with 4.5-inch backspacing. Check clearance on the actual vehicle.
Professional installation and alignment are required. Work includes removing the factory coil buckets and rivets, drilling the frame, trimming the inner fender wells, checking A/C-line clearance, relocating brake/ABS lines, checking 4WD vacuum-line routing, clamping the rear leaf packs for center-pin and add-a-leaf work, and drilling the upper leaf plates. Follow the manufacturer instructions for the eight-inch suspension height, limit-strap configuration, clearances, re-torque and maintenance requirements. Do not loosen pressurized reservoir components or remove factory-preloaded coil springs.
