The OBX Helical Limited Slip Differential powers both drive wheels under nearly all conditions, instead of just one. With an ordinary open differential, standard on most cars, a lot of precious power is wasted during wheelspin under acceleration. This happens because the open differential shifts power to the wheel with less grip(along the path of least resistance). The OBX Helical limited slip differential however does it just opposite. It senses the which wheel has the better grip and biases the power to that wheel. It does this so smoothly and constantly without ever completely removing power from other wheel .Power to the ground. The Helical limited differential is a torque sensing LSD that features smoothing operation and superior responsiveness. The unit does not require the special oil like the clutch type limited slip differentials.
