This is a pretty much standard U bolt made to fit a D60/8.8 axle. The exception being that they have .625" (5/8) Rolled Threads for extra strength and the threading is 5" long so they will fit! Cut off what you don't need after they are on for a perfect fit! They are also Grade 8. If they fit use them (if they don't fit drill your plates until they do)! All of our U-bolt plates are recommended to use 5/8" U bolts. Comes with Tallnuts and Thick cut 1/4" Washers.
