How silly would it be for me to remove the crappy no-name brand rear springs the previous owner of my 4R put in, and put factory (or drop in replacement) air bags back in? I'm not 100% on the scope of work needed to make that happen, but at minimum bags and sensors. The air compressor is still in, and the only reason I'm considering this, is because I hear it run occasionally. The 'tank' is also still mounted to the frame, but it looks like some of the air lines were just cut and they don't look like a standard connector. I'm not opposed on the surface for additional headache from the added complexity of the RAS. However, it seems like it would be nice to have on the off chance I end up needing to pull something.
