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 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 of our products, 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 extras truly make this Aluminium case the ultimate Ford 9" case. All our aluminium third members come with 12 point through bolts which gives us an advantage over our competition.
The TORQUE WORM 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 grater 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. The outer cases made from 8620 Chrome-Nickel-Moly Steel and the case hardened for long life and improved strength.
The GEARSETS used are HI-PERFORMANCE 8620 Chrome-Nickel-Moly Steel. CNC machined from high quality forgings to our exacting specifications and then heat treated to obtain high impact and durability. Then lapped to allow for correct tooth contact and smoothness and for use in the performance market. The 8620 Gearset has proven itself in all forms of motorsport over the past 30 years.
Some of the available ratios are (but not limited to): 3.00, 3.25, 3.50, 3.70, 3.89, 4.11, 4.30, 4.56, 4.88, 5.14, 5.43, 5.67, 5.83.
YOKE: Includes a 1350 billet steel yoke, fully CNC machined to our specifications.
ASSEMBLY: Assembly has been carried out by our differential department. Quality is assured with 40 years experience in the Differential Repair Industry and full involvement in all forms of motorsport from V8 SUPERCAR To Group 1 Drag Racing.
NOTE: These 3rd members are to be used with a mineral based oil of a range of EP140 Extreme pressure at a minimum, NO split grades eg. 85/140 (These are not recommended), failure to use the correct oil can result in gear damage, noise and may void your warranty.
