Extended pin boxes do not change the width of the 5th wheel. If 1/2 the width of the 5th wheel is greater than the hitch kingpin bore centerline to cab distance, then contact is a given at (or possibly before, depending on front cap configuration) 90 degrees. The slider moves the hitch kingpin bore centerline rearward, so it provides additional clearance at 90 degrees that the extended pin box does not.
