Ford 9" 31 Spline Posi Limited-Slip Differential / Torque Worm TrueTrac Unit
The Torque Worm is a torque biasing 6 pinion gear type limited slip carrier. This unit is preloaded allowing for a faster reaction. Torque Worm design uses 6 pinion gears verses 3-4 pinion gears that competitors offer which means less stress on each gear and the load is spread over a greater surface area reducing wear on all internal components. Internal components are made of EN36 material and the outer case is made from 8620 Chrome-Nickel-Moly steel and case hardened for improved strength. Also available in 28 and 35 spline count.
