I have a set of overloads off a F350, but my u-bolts are too short. Anyone know what the width of the axle is? I can't remember if it is 3.5" or not. I believe the bolts are 5/8" and I need them about 14" long.

 

im 99% sure its a 3.5" diameter axle tube, also, theres spring places that will make you custom bolts in like 15min. i made a 1.5" lift block for my friends 2wd 2012 f150 and the place by me measured everything and had me out the door with bolts in about 15min
