FREESPIN BENEFITSUpdated 8 months ago

1. Improved Durability and Longevity

• OEM unit bearings are sealed and non-serviceable. Once they wear out, they must be replaced entirely.
• The Dynatrac kit uses serviceable tapered roller bearings, which can be greased and maintained, lasting significantly longer—especially under heavy loads or off-road use.

2. Reduced Maintenance Costs

• When OEM unit bearings fail (and they often do under stress), replacement is expensive.
• With the Free-Spin Kit, you can simply replace individual bearings or seals instead of entire hub assemblies—much cheaper over time.

3. User-Serviceable Components

• The kit uses a spindle and bearing system similar to older Dana 60s, which are familiar to many DIY mechanics.
• It’s easier to work on and doesn’t require specialized tools or replacing entire assemblies.

4. Increased Front-End Strength

• Dynatrac’s spindles and hubs are stronger than factory unit bearings, making them more suitable for heavy-duty use, larger tires, towing, or off-road abuse.
• The kit can handle more lateral and radial load than stock, reducing front-end deflection and premature wear.

5. Manual Locking Hubs = Better Efficiency

• When you unlock the hubs in 2WD, the front axle shafts, differential, and driveshaft stop spinning.
• This results in:
  • Better fuel economy
  • Less wear and tear on your front axle components
  • Quieter highway driving

6. Better Drivability & Steering Feel

• The Dynatrac system reduces drag and rolling resistance when in 2WD.
• Many users report a noticeable improvement in steering responsiveness and reduced wander, especially in lifted trucks with larger tires.

7. Enhanced Off-Road Capability

• If you pair the Free-Spin Kit with selectable lockers and upgraded shafts, it becomes part of a much more robust off-road drivetrain.
• Manual hubs give you the flexibility to engage/disengage 4WD as needed.
