what diameter rod are 14 bolt FF U bolts made of ? anyone know for sure ??
thanks for anything
If you would have done a search, you would have found this...
not having any luck, yes i do search for stuff on this forum, the best as i can tell these bolts are made of 5/8" rod and are 4" centers
that sound right ?
5/8 stock, 3 3/8 ID, 8 inches and longer depenfing on your rear suspension.
did some measuring of the u bolt plates off the 74 3/4 ton and 5/8 rod would be extremely tight fit in the bolt holes of the plates and i measured the diameter of the bolts on the '81 1 ton dually cube(large) van out here and its got 9/16" bolts pointing down style setup, its a 10,000lb GVW truck, so hmm... i think ill just go with 9/16 so that i know ill have no trouble with fitting bolts through the plate holes, if 9/16" is enough for a big huge 1 ton dually van then i would think its overkill for a 3/4 ton pickup
If you see a big cube van on the rocks let me know...I want pic's!!
The 5/8" stock goes through the plates just fine.
hehe, i know but wierd how a 1 ton uses 9/16" and why 3/4 ton would use 5/8" hmm..
Mine came out of a 1-ton and it uses 5/8". I did have a little problem getting them in and out of the top plate though, that was kinda annoying.
It is supposed to be tight, if you get the bolt at an angle you will never get it in, so Yes I say go with 5/8".
but technically the diameter of the rod they ar emade of wont affect or change angle of the legs of the bolt, but instead the width of the U bolt would affect the angle of the legs and location of the ends of them in comparison to the location of the holes in the plates. how some ppl have 3 3/8" plates and bolts and some have 3 1/2" plates and bolts ill never know, but ive got 3 3/8" on the 74 3/4 ton and same on the '81 G30 dually van out here and the van is 9/16" bolts anyways with its 10,000 GVW,
thanks for any further info on this, would be glad to hear it!
