Fitment & Compatibility

Measure 2.66 inches of axle offset at the Small Ford housing interface and check all flange and bearing-retainer dimensions before ordering. The Town Car table entry below is conditional on the actual axle configuration; do not select this kit by vehicle identity alone. AERO4 hydraulic calipers provide the service brake, while separate motor-operated parking calipers use the supplied controller and wiring harness. Electronic parking does not replace an emergency stopping system. Allow for wiring protection, the two-piece rotor envelope and separately sourced flexlines.

Use the fitment table below to check each listed year, model and brake configuration alongside these installation requirements.
