We do offer leaf spring shackle bolts as separate items. The linked page will show you all lengths, including 4-inch and 4-1/2-inch. In your required 9/16-inch diameter the longest bolt we have is the
Redline # 34007-187-00 which is 3-7/16-inches. The 4-inch and longer shackle bolts are different diameters, such as the Redline # 38-4TB which is 4-inches x 3/8-inches diameter.

You will be better off using hangers of the correct width for your 1-3/4-inch springs, rather than shim them. We do offer hangers for 1-3/4-inch wide springs in various heights with a 9/16-inch bolt hole diameter and these can be seen on the link provided.

I also linked our main page for all trailer suspension components where you can check for individual components that will work for you if a complete kit with all the correct items does not happen to be available. Also included are two articles on trailer suspensions which may be of interest to you.
