I already have lockout hubs, why would I need this kit?

You are correct that you may already have lockout hubs, however, the factory hubs a notoriously weak and function marginally at best.  The benefit of manual lockout hubs is not the only reason you need this kit.  Factory unit bearings are very expensive to replace and will leave you stranded on the road typically at the most inopportune time.  Sometimes your unit bearings will give you a warning that they need replacement, but this has not been the case in our experience.

What are some of the benefits of the SpynTec™ kit?

The wheel bearings in all SpynTec™ kits are fully rebuildable and maintainable.  If you keep up a standard service regimen, you can grease your wheel bearings and replace them as required for a fraction of the cost of new unit bearings.

Another benefit of the Ford SpynTec™ kit is a shaft spline increase to 35 splines.  If you use your truck hard, you may have already been through a few shafts.

I have a dually, can I use the factory wheel adapters?

Your factory adapters will work on the Ford conversion kit.  There is typically a slight amount of buffing that will need to be completed since it is a rough cast part on the inside diameter.

How do I know if I have coarse thread or fine thread studs?

There was a switch from coarse thread to fine thread studs halfway through the 02 production year.  If you have an 02 model year truck, please contact us and we’ll get you squared away.
