Dynatrac Free-Spin Kit, 2005-2014 Ford F250/F350, w/DynaLoc Hubs, SRW & DRW - FO60-3X1104-F

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.
