Dynatrac Free-Spin™ Heavy-Duty Hub Conversion Kit with DynaLoc™ Hubs for Ford F-250 and F-350 (2005–2014)

The Dynatrac Free-Spin™ Heavy-Duty Hub Conversion Kit is engineered to replace factory unit bearings on 2005–2014 Ford F-250 and F-350 trucks with a fixed spindle design for increased strength, improved serviceability, and smoother long-term performance. This system eliminates the common weaknesses of sealed unit bearings and is ideal for towing, daily driving, and off-road use.

This kit includes Dynatrac’s DynaLoc™ locking hubs, providing reliable engagement, greater strength, and a shorter hub profile for improved clearance. The reduced hub stickout helps minimize trail damage while delivering dependable 4WD operation.
