Dynatracs 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 Dynatracs Dynaloc manual locking hubs for greater strength, reliability, and a short, custom machined bezel to improve your hubs looks. All parts are made in the USA.

I have two Dodges and I have installed this on both trucks now. the hardest part of the install is getting the factory hub assembly out, Snap-on makes a tool that helps with the removal and will take about an hour to disassemble. the only recommendation that I have is spend the money to get Stage 8 Xlocks for a DANA 60, due to the heavy weight of a Cummins the wheel bearings tend to wear and the wheels will loosen about every 5k miles.
