Dynatrac Free-Spin™ Heavy-Duty Hub Conversion Kit with DynaLoc™ Hubs for Ford F-250 and F-350 Super Duty (1999–2004, Fine Wheel Studs)

The Dynatrac Free-Spin™ Heavy-Duty Hub Conversion Kit replaces factory unit bearings on 1999–2004 Ford F-250 and F-350 Super Duty trucks with fine wheel studs with a fixed spindle design for superior strength, serviceability, and smooth long-term performance. By eliminating sealed unit bearings, this system reduces front-end wear and improves durability for towing, daily driving, and off-road use.

This kit includes Dynatrac DynaLoc™ locking hubs, delivering improved hub function, greater strength, and a shorter profile for better clearance—helping reduce the risk of hub damage on the trail.
