CASE: The aluminium available today is vastly different from that of years past. Technology has made aluminium products stronger and more durable. Knowing this, we at Traction Drive Systems decided to have an aluminium Ford 9" dropout case built. You may say to yourself, "That's nothing new, other companies have been making them for years," and that's true; but as in every Speedmaster Traction Drive Systems product, we look closely at what's out in the marketplace and how it can be improved. Our aluminium cases are made from A356-T6 aluminium, our bearing caps are one-piece billet, with a through bolt design and extra material is added to the bearing caps. These cases are offered in 3.250" bearing diameter to accommodate 28, 31 with the use of PCE207.1002 and 35-spline carriers and spools. These extras truly make this Aluminium case the ultimate Ford 9" case, rated to 850 horse power. All Traction Drive System Aluminium third members come with 12 point through bolts and a Daytona style pinion support, which gives us an advantage over our competition.
