Mazda MX5 Mk1 Mk2 NC Miata 94-05 TorqueWorm Helical Gear Limited Slip Carrier LSD Speedmaster CNC ported cylinder headsThe TorqueWorm is a torque bias, 6 pinion gear, 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. The outer case is made from 8620 Chrome Nickel Moly steel
