7 Inch Lift Kit w/ Radius Arm | FOX 2.5 Performance Elite Coil-Over Conversion | Ford F250/F350 Super Duty (20-22) 4WD | Diesel

Built for diesel Super Duty owners who need 7 inches of lift, 38-inch tire clearance, and rock-solid driveline geometry. This radius arm kit pairs FOX 2.5 Performance Elite coil-over shocks up front with either a lift block or leaf springs in back — giving you the stance and capability to run serious rubber while keeping factory driveshaft angles dialed in.
