Description

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" bearing diameter to accommodate 28, 31 and 35-spline carriers and spools. These extras truly make this Aluminium case the ultimate Ford 9" case, rated to 850 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. 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.  


YOKE: Speedmaster TDS  Billet yokes are a long style unit fully CNC machined to our specifications.


ASSEMBLY: Assembly has been carried out by the Speedmasterª TDS differential team. Quality is assured with 40 years of experience in the Differential Industry and full involvement in all forms of motorsport from V8 SUPERCAR To Group 1 Drag Racing. Our Technicians are on hand to discuss your differential requirements, questions, and upgrades.
