Dynatrac Free-Spin Kit, 1999-04 Ford F250/F350, w/DynaLoc Hubs, Fine Studs - FO60-3X1104-H

The Dynatrac Free-Spin Heavy-Duty Hub Conversion Kit for 2005-14 Ford F250 and F350 Super Duty trucks is designed to replace the factory unit bearings with fixed spindles for superior strength and smooth performance. Factory unit bearings are not serviceable, can’t be inspected, and are a known failure point. This kit fits both single-rear-wheel (SRW) and dual-rear-wheel (DRW) trucks. It also includes Dynatrac’s innovative DynaLoc locking hubs that deliver improved locking function, are three times stronger than other locking hubs, and their shorter profile affords better clearance, reducing the chance of hub impact damage.

Replaces failure-prone factory unit bearings 35-spline, 1.50-inch outer shafts Features DynaLoc locking hubs for maximum performance For fine wheel stud applications Strong heat-treated chromoly spindles Easy to maintain for longer service life Top-quality bearings reduce wear and increase fuel economy

Trucks with dual rear wheels will require the use of a special dually wheel adapter. These can be purchased through Arrowcraft (248-280-0210). These parts have been made to work specifically with Dynatrac’s Free-Spin Kit.
