So I ran into this guy who had a 2 door 4" lifted Cherokee and we started having a nice Jeep-versation. Then he told me how his boss said something about some electrical part or something from a GM 4x4, perhaps like a Blazer, that you could swap out with the Jeep one and it will give you better performance. Examples used, Better Top-end and alot faster starts. He said there was little modification to make it work. Anyone know anything about something like this? If you do PLEASE share. Thanks
