Description

HD vs HD Pro

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 lightweight SPOOL gives you the traction you need by locking the axle shafts together, forcing your rear tires to turn at the same speed. They"re CNC-machined from forged chromoly steel to provide a more rigid ring gear mounting. This eliminates gear failure caused by case deflection or differential side-gear failure.

 

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.
