The Dynatrac Free-Spin Heavy-Duty Hub Conversion Kit for 2005-2014 Ford F-250 and F-350 Super Duty trucks is designed to replace the factory unit bearings with fixed spindles for superior strength, and smooth performance. This kit fits both single-rear-wheel (SRW) and dual-rear-wheel (DRW) trucks. This kit includes DynaLoc locking hubs, providing improved locking hub function, greater strength and a shorter profile for better clearance that reduces the chance of hub impacts on the trail.
Known for its brawny axle assemblies, Dynatrac got its start in the early 1990s when founder Jim McGean was building axles in his garage for off-road enthusiast friends. When others resorted to low quality parts from overseas, he took a stand and maintained production here in the states. Dynatrac's innovations include the high-clearance ProRock 60, Free-Spin hub conversion kits and heavy-duty DynaLoc locking hubs. Every axle manufactured undergoes 117 inspections during its assembly for quality assurance and the Huntington Beach, California-headquarted company has a deserving reputation as a manufacturer of high quality innovative components.
