Traction control has nothing to do with a lift ford is using the abs sensors to sense speeds and the brakes for the traction control. For a 3" lift I assume you are using torsion bar keys make sure to read up on them in the sticky under suspension tech.
Help I just bought a 2011 Ford Ranger XLT. I am being told that it cannot be lifted with a suspension lift due to the traction control. Ever heard of that? I only want to lift about 3 inches. Any advce??
