1. The Full Traction front coilover and four-link conversion is made for '99-to-'04 Super Dutys and comes with everything you see here. You can order King coilovers directly through Full Traction or you can supply your own with the suspension. If you're not ordering your King shocks through Full Traction, then remember to order a single rate, 500-pound-per-inch coil on top of the coilovers.
You can use either a 2.5 or a 3.0 coilover with this suspension, with either an 8-inch-stroke or 10-inch-stroke coilover shock, depending if you want 6 or 8 inches of lift on the front of your Super Duty.
