CT WTB 4x4 rear U-bolt - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Patsfan34 · 12-16-2010, 10:35 AM

I need one rear U-bolt with both bolts. I would prefer a matching one like pictured below. This is 68 GMC 1/2 ton 4x4 frame but I assume most of the U-bolts for 1/2 ton 4x4s are the same. The bolts measure 7/8s. I have 5 leafs in the leaf springs. Shipping would be to 06615. Thanks, Neil

Hi Neil, I have one from a 72 I can send you. I'll get a picture and measurements for you tonight. Thanks, Sharpie

Is that the stock setup? I don't recognize that saddle....I thought they used a cast saddle and it went on the bottom of the axle tube with the u bolts facing down...more of a squared u bolt that wraps around the leaf pack instead of axle.

I'm not 100% sure mine is the stock set up but I think it is. Blazerman I've seen what your talking about on trucks with a lift kit. The square u-bolts are usually for holding the blocks in for the lift kit, at least that's what I thought.

Pics of stock 72 U-bolts. Looks like these came from a K20, also a new set same bend just smaller diameter. 4 " wide outside 8 1/2" long 1/2" and 5/16" diameter respectively. Let me know if one of these will work and I'll get it headed your way. Sharpie

Dennis I'm pretty sure one on the left will work. Can you just confirm the bolts are 7/8s? PM me what I owe you with shipping and I will paypal you sometime this weekend. Shipping to 06615. I will take the one that requires the least amount of wire brushing and nice straight threads. Thanks again so much!

Hi Neil, the nuts on those are 15/16ths and 3/4 on the smaller ones which fit my stock sadlle. Sharpie

I have always heard that you shouldn't reuse U-bolts. I am guessing it has something to do with stretching/yielding and not up to 100% strength.

Anyway, a spring shop can bend you new ones for about $12.
