This is a Spring Hanger made for 2.5" Leaf Springs and the inner width is 2.75" for bushing room and it has an additional "ramp" piece for greater rigidity. This particular style hanger can be used to add 1" + Wheel Base when used extending beyond the frame, the Spring Pin location is aligned with the leading edge of the bracket itself, that can come in handy. We have used them facing front or rearward, the ramp can act as a skid too. This can be used when mounting any 2.5" spring on any vehicle.
