u-bolt size - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm currently lowering my suburban a few inches and also installing a shock relocater kit from cpp. I cannot get the nuts off of the U-bolts to install the bottom shock mount. I've tried heat and put a pipe on my ratchet and still nothing. I think I'm going to have to cut them off.

Anyway, my question is will 1/2" U-bolts be sufficient?

The stock U-bolts are 3/4" diameter. The only U-bolts that I can buy locally are 1/2". I've checked all the auto parts stores and I can't find a suspension shop locally. I can order a set from Napa (5/8" and will still take 3 days) or I can order a set online.

Any opinions. Thanks

They need to be the larger (3/4"?) diameter.

The typical local auto parts store 1/2" units are usually for leaf applications. They slip over the housing tube 90° to the tube so they only need 3"ID. The truck arm arrangement requires more ID clearance because they're not @ 90°.

These are available from more than one board supporting vendor as well.
