The correct hanger spacer when using the Triple-Axle Trailer Hanger Kit part # APTT5 with the 4-Leaf Double-Eye Spring part # e54SR is 29-1/2" from the front hanger to the center hanger, 34" between the center hangers, and 29-1/2" from the second center hanger to the rear hanger. Please note, you will also need the U-Bolt Kit for Mounting Kit part # APUBR-1 in order to mount the leaf springs to the axle.
