The Dynatrac Free-Spin™ Heavy-Duty Hub Conversion Kit for 2012-2019 Dodge 2500 and 3500 trucks is designed to replace the factory unit bearings with fixed spindles for superior strength, and smooth performance. 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.

• Heat-treated chromoly spindles
• Top-quality bearings and seals
• 35-spline, 1.50-inch outer shafts
