Chrysler 9.25" Rear 31 Spline TorqueWorm LSD Limited Slip Differential Speedmaster billet aluminum valve bodiesThe 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.
