All rack and pinions have rack rotation. This keeps the rack from binding. On our center-take-off racks the rack rotation may seem like a lot at the end of the center-take-off bar but it is still the same amount at the rack as any other rack and pinion. Here is a picture of what a center-take-off rack looks like. There is a large boot in the center of the rack with a bar coming out of the middle. Then the tie rod ends come off of that center bar.
