CASE: 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" & 4.000" bearing diameter to accommodate 28, 31, 35 and 40-spline carriers and spools. These extras truly make this Aluminium case the ultimate Ford 9" case, rated to +1000 horsepower. All our aluminium third members come with 12 point through bolts and a billet pinion support, which gives us an advantage over our competition. The TORQUEWORM is a torque biasing 6 pinion gear type limited-slip unit. This is a preloaded unit allowing for a faster-reacting unit. Unlike our competitors that only use 3 or 4 pinion gears. The use of 6 pinion gears means the stress on gears is spread over a greater surface area, reducing the load on all internal components. The internal components are made from EN36 Material as used in racing such as V8 SUPERCAR.
