There is nothing wrong with your corporate 10. Since you want to change gears, also install a quality carrier like a Detroit, Yukon or Eaton. I see no need to swap the axle unless your current one has structural integrity issues. There is a vendor in the sponsor section of this forum that sell ring and pinions with carriers at a pretty good price. Check it out if you get a chance http://www.ls1truck.com/forums/spons...xles-more.html
