Review on 🔧 Supreme Suspensions - 3" Front Leveling Kit for Ford F250/F350 Super Duty: T6 Billet Aluminum Coil Spring Lift Spacers with Shock Mount Extenders (Silver) by John Fenton

3 inch coil spacers worked well. As another reviewer pointed out, it helped to use a bottle jack in the frame to widen the opening to attach/remove the springs. The shock shims weren't quite right, I had to file them down to push them through the frame bolt, so I removed a sprocket. The instructions don't list torque values, so you'll have to look them up yourself. I think they should give you the torque ratings for their new hardware. .The installation wasn't difficult, only took about 3 hours (even with filing the shock absorbers). In my photos you can see where I painted over the holes with silver where they don't quite line up. I don't know if that's the cause will be some issues but I believe by the time it wears out I'll just get longer shocks.
