Cetane there must have been something wrong with yours because I know several guys with them and they steer like a Cadillac and the trucks have 37"s on one and 24" semi's on another and it feels great
I have an ARG in my BURB as teh stock GM box was about worthless with the extra front end weight after my engine swap. Been pretty happy with it except for it being LOOSE out of teh box(had to go through and adjust it which is not what I expected to do to a brand new steering box).
