This is a Spring Hanger made for 2.75" or 2.5" Leaf Springs with the large bushings (GM style) Leaf Springs. The inner width is 3.0" for bushing clearance and it has an additional "ramp" piece for greater rigidity. This particular style of hanger can be used to add 1"+ WB 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. Sold in pairs.
