10.5 x 4.1 in. Down 30 Spline Pro Traction System

Grip Pro traction systems are the latest design in differential technology. They combine the smooth operation of a limited-slip differential, with the strength of a fully machined, forged steel case. Using 3x2 spiral gear engineering, the Grip Pro delivers progressive and variable traction. Based on throttle input, you are in control of how much traction is applied. These differential systems are great for use where finesse is just as important as brutal traction. On the road or track, in the rain or snow, Grip Pro is a winner The systems come fully assembled and there are no friction plates so you can use any gear oil you like, including full synthetic and racing lube.
