GM 12-bolt U-bolts

HandOverFist · 12-07-2013, 10:20 AM

Anyone have a reliable link/source for U-bolts for a Chevy 12-bolt housing? I'm in need of 8' to 9" length due to the use of lowering blocks.

Go to your local spring repair shop, they can make them any length you need.

If I understand correctly Chevy uses a 3-1/16" inside dimension?

Just had a local spring shop do these for a Nova mono leaf 12 bolt:

3 1/8" inside-to-inside and 7 1/4" leg length (measured from the outside top of the 'u'). When installed, there is 2" of thread below the Cal Trac mounting plates.

Not the exact info you asked for, but might give you some reference for length.... -Al

P.S. I like the Camaro build pics.

My local parts store had them in stock.

Yeah, I need at least 8" because of the 1" lowering blocks on our car. I don't know of anyone local in my parts.

Perfect Alan - I was looking at a set there earlier but they would not have them until the 18th. Don't know why these didnt show up in the search.

Edit: Just found the same ones on the Summit site as well... http://www.summitracing.com/search/p...0Leaf%20Spring
