Q: Will this kit work on a 1999 F550 4x4 with course thread wheel studs? Answer this question
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.
