You might ask why did we change this popular kit? Clean, good, usable 1987-1993 spindle cores are getting harder and harder to find and much more expensive. 

This kit was developed for the end user to modify their spindle.  This does not require the spindle to be removed from the car (it can be, but not necessary).

What is required?

  • A tool to cut the spindle (factory ears will be removed)
  • Drill and tap: recommended but not required.
    • We sell a separate install kit (1979-1993 Foxbody Mustang Spindle Modification Kit) that with all the pieces to make install easier, including a fixture/locator to drill the spindle.

Look over the instructions and pictures carefully.

The modification is not hard to do, and someone with simple mechanical skills can do them, but we want you to be aware of what you need to do before getting the kit.
