Mine was the same when I got it... no trans cooler back when I had the E4OD and def no oil cooler. Just the wiring and quad shocks...I always wonderd that. Mine is kinda a strange one. I had the quad shocks, and rear wiring, but no trans cooler, or oil cooler. Does have the big rad, but thats probably part of the AC packedge.
Much to my surprise, a previous thread on the subject indicated that it made the ride worse. The argument being that newer shocks did a better job than the original ones so doubling them up was over kill. I have double shocks on mine and the ride is pretty stiff.Now, does quad shocks really increase ride quality? or is it mearly for added support during towing?
