03. New 4340 chromoly outer axleshafts replace the stock shafts. South Bay Truck & 4x4 noted that the ears of Yukon’s chromoly axleshafts were thicker, but there was no interference at full steering lock. Since’94-to’01 Ram 4x4s have ABS sensors that take readings off the spinning outer axleshafts, ABS systems will not work with the Spin Free kit since the new axle assemblies will no longer be spinning with the front wheels (when in 2WD). Therefore, the new shafts are not designed to take the ABS rings.
