The ultimate differential for your Weddle HV or MD/S4*/S5* trans. Weddle Industries' new Automatic Torque Biasing limited slip 
differential has the ability to transfer power to both wheels smoothly, automatically, and without the use of friction discs or drive plates.

The Weddle HV-520 diff features an extremely durable planetary helical gear design, with 9310 steel gears running in case-hardened steel bodies. Critical housing dimensions are precision ground after heat treat, and all internal components are made from the highest quality materials, with ARP® fasteners used throughout. Minimum weight was a key design goal: the HV-520 is only 0.84kg (1.8 lbs) heavier than the standard open differential it replaces. 

Application: Weddle HV, MD, S4*/S5*
