This listing is for a NEW 31 SPLINE TORQUE WORM Limited Slip Differential FOR A FORD 9 INCH With STOCK CASE 2.89 CARRIER BEARINGS.  It works like a posi unit.  It supplies power to the wheel that does not get the power off the line and lets you make turns like an open rear end car.  I use this unit in my own car and it works great, I get some awesome Burnouts.  I run it at the track 2 times a year and the rest of the time is just going to car shows and driving around town.  So if hit the gas and your sporting a PEG LEG YOU NEED ONE OF THESE UNITS!  This unit is good for up to 700HP.

UNIT WILL SHIP OUT IN 1 to 2 DAYS AFTER PURCHASED.  IF PURCHASED ON SATURDAY OR SUNDAY, IT WILL BE SHIPPED OUT MONDAY EXCLUDING HOLIDAYS. 

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 the gears is spread over a greater surface area, reducing the load on all internal components.
