No, not really. I don't know much at all about what guys do to the suspensions of 1/2 ton trucks, or what is offered by the aftermarket for them.

Personally I have been looking at two different suspension systems for my 2 ton truck, one is a 4 link, (actually a 5 link) the other is similar, but different, both are air ride.
This one from Kelderman: http://www.keldermanairride.com/productdetails.php?id=450%2F550FRD4LNK
And this one from Hendrickson: http://www.hendrickson-intl.com/products/product_detail/has_single.asp

I think I'll run my leaf spring suspension (new springs) and air helper springs for a while, and be on the lookout for a used 12,000lb Hendrickson suspension, and/or save my money for a new Kelderman or Hendrickson suspension.
