I have a '12 3500 4x4 CC short bed with 33x20's. It has a slight rake from the factory. I have a 2.5" leveling kit, but that's too much. I still want a small amount of rake, and the 2.5" sets it level, or possibly a tiny bit high in the front. I'm looking for something around a 1.5" and can't find anything. Am I stuck getting my local machine shop to make some, or does anybody make a 1.5" spacer?

 

Try these guys...they make these leveling blocks, maybe they can fab a set for you the size you want.

You could always do the mini pack add-ons. They will raise the rear by 1 inch and provide a much better ride too. http://www.koreraceshop.com/kore-mini-packs.aspx Carli also has a rear progressive spring pack that raises the OEM load capacity and lifts the rear by an 1" also.
