Description
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 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 Torque Work unit is available in 28, 31 and 35 spline counts.
