This is a Spring Hanger made for 2.75" Toyota FJ60 Leaf Springs, the springs are 2.75" wide but the bushings make for an overall ID of just over 3 3/16". It has an additional "ramp" piece for greater rigidity. This particular style 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. If you wish we will weld in the ramp for an additional $8. Sold in pairs.
