Dynatrac’s Free-Spin heavy duty hub conversion kits are designed to replace the factory unit bearings with a fixed spindle design for superior strength, reliability, safety, and performance. While the factory unit bearing is non-serviceable, cannot be inspected, and prone to failure, the Free-Spin Hub Conversion offers ease of maintenance, a much smoother ride, greater fuel economy on Dodge trucks, and longer axle life. The simple bolt-on kit includes common and serviceable Timken bearings, chromoly spindles, cast nodular wheel hubs, Warn Premium manual locking hubs, and massive 1.50” diameter, 35-spline outer axle shafts. Consider an upgrade and substitute the Warn Premium locking hubs to Dynatrac’s Dynaloc manual locking hubs for greater strength, reliability, and a short, custom machined bezel to improve your hub’s looks. All parts are made in the USA.
