Search on forum doesn't work well @ all. Google or Bing allow you to specify a site to search.
For example using google...
site:ifsja.org add a leaf
site:ifsja.org leaf spring center pin size
I have used AAL(s) on Jeeps and other vehicles, they work fine most of the time unless the springs are total garbage.
Some people complain they're stiff/ride hard this has not been my experience but some people have differing opinions on ride quality.
When new they require a break in period just like new leaf springs, and mellow some after this.
