    I am adding 2 new leaf springs and putting on 10 packs vs. the old 7. What size are stock u-bolts? Need all 3 demensions. I can get extra thread to accomodate extra leafs. Thanks !

    When I replaced my 7 packs with the heavier duty 10 packs, I found that the same u-bolts accommodated both spring packs. If you still need information though, check out this thread posted by McRuff http://www.earlycj5.com/forums/showthread.php?t=81515&highlight=u-bolt FWIW, I found that the 10 packs on the front were just too stiff. Later this afternoon I am going out to the shop and removing a couple of leaves. Just my opinion.

    Thanks....good advice...i will be plowing with the jeep alot this winter so its more about additional weight and support of plow and rear weight vs. a smooth ride...so I am hoping the 10 packs work out. The chart is great from Mcgruffs thread, but I'm still not sure which ones are the stock dimensions as are there are many to choose from. It has original spring plates, are they
    1/2 diameter? I was hoping to just order vs. pulling the old ones to get all 3 measurements...txs....

    You need to match the u-bolt diameter to the axle you have. Your year of Jeep should have a tapered axle Dana 44 which has a 2 1/2" diameter. Length will be dependent upon spring pack thickness. I can't remember off the top of my head the Dana 25 axle housing diameter and diameter of the u-bolt that goes over the pumpking but someone hopefully will help with that.
