Please note for the Fox Body and SN95 owners, depending on how low the car is or suspension setup we strongly recommend that you verify clearance of all components (especially the spare tire well). For S197 owners this is a good time to make sure your vehicle has functioning bump stops. Also, before installation make sure that you can loosen and remove the factory fill plug on the front of the housing.


TOOLS REQUIRED:

  • Socket Set
  • 3/8" Drive Torque Wrench
  • Shop Towels
  • Quality Brake Clean
  • Correct Weight & Amount Of Gear Fluid
