    I just purchased a used 4" lift for a 1979 K5. Rear blocks and leafs in the front. Problem is there are no U bolts. Could someone measure theirs and let me know the lengths?

    Thanks

    Is that the rear or front? I think I need the rear more so.

    Thanks

    3" diameter axle tube, 9/16" or 5/8" thread, 10-12" long are what mine were for 1/2 ton axles. I got them made at a spring shop for $5 each.

    Fronts are the same except for the big one, it's 3 3/8" diameter I think. The big one is the inside one on the passenger side, the one that goes under the pumpkin.
