I would like to make my 2000 ranger 2wd xlt 3.0 with rear abs have 4 wheel abs. I know I would need to get the sensors, rotors, the pump and the module is there anything else that I would need? Is that kind of mod possible or really be cost effective? Would the PCM need to be replaced? What about wheel cylinders and/or calipers?

 

The GEM, the under hood harness and probably the dash harness would need changed. You would also need front brake lines, rear brake line, spindles and rotors. Rear ABS gets the speedometer signal from the GEM and 4wabs get the speedometer signal from the abs module under the hood.
