Fitment & Compatibility
Match the Ford Explorer 8.8 housing pattern, center registration and measured 2.54-inch axle offset. The 12.19-inch vented rotor incorporates the drum surface used by the internal parking shoes. This is not an MC4 or electric parking kit. Cable hardware, adapters and hydraulic flexlines are not included; choose them for the completed axle installation. Follow DS-1441 to seat the backing plate, align the Dynalite and adjust the shoe clearance. Check the wheel drawing for the actual wheel rather than relying solely on its 15-inch nominal diameter.
