Installation took longer than expected. Jun's bumper is the worst. Do yourself a favor and just grind the nut at the top of the frame. Additional supports were not required to access my truck's axle. There was a 3/16 to 1/4 inch gap, but after adding some air they touched the axle as intended. Pay attention to the right and left bottom bracket so you don't have to swap them around like I did. . Mine was installed on a 2005 F350 as a twin. I just finished them today. Next week I will upload a big truck and update it if necessary. The price was great compared to other online retailers. Watch the trailer video for a full installation. This can save you time.
