I don't know, I haven't heard of that. I've been out of the diesel scene since 08 so I don't know the latest and greatest stuff that's out there. If you've got info I could use please elaborate!
check with g2shuck..or the folks at mtw...maybe even try strokers unlimited, they do some wheel upgrades... I know the ww2 for the 6.0 from dieselsite is supposed to give great gains....they are all sponsers here
