Running locking differentials ensures that power is going to each wheel, but with power comes responsibility. If the tire with traction also has power, the 4x4 will move forward, break traction, or break parts.

Our new 30-spline Superior axleshafts are made in the USA with rolled splines of dual heat-treated chromoly.
