This FreeSpin Kit is a great choice for 1999 - 2004 Ford F - Series trucks with 7.3L Powerstroke engines. It replaces factory unit bearings with fixed spindles for maximum strength and top - notch performance. The locking function is much better, and the shorter profile gives better clearance, reducing the risk of hub impact when off - road. Part Number: FO60 - 3X1104 - H. Features include wheel studs, heat - treated chromoly spindles, high - quality bearings and seals, 35 - spline 1.50 - inch shafts, wheel hubs, DynaLoc or WARN locking hubs, and all necessary studs and hardware. Trucks with dual rear wheels need a special dually wheel adapter, which can be bought through Arrowcraft or us. These parts are designed to work perfectly with Dynatrac’s Free - Spin kit.
