These U-Bolts will NOT fit my 2003 F250. The rear axle on my 4x4 XLT is 1/2 inch thicker than these U-bolts can handle. My mechanics tried to change their shape so I could use them in search of a suitable replacement. The first U-bracket broke when putting it on. proof that hardened steel can't be handled, I guess. Super disappointing and disappointing purchase
