The tremendous torque loads generated by a Pro Stocker during acceleration can actually distort a fabricated steel rear end housing, bend the axle, and generate side-loads on the axle bearings. Not only does this hamper performance, but it can contribute to axle "walk out" and potential breakage.

This kit contains all of the parts required to convert the MW symmetrical, Lamb standard, or Olds type axles to the spherical self-aligning wheel bearings to compensate for any housing distortion. The housing ends are 1-1/2" long and will accept butt-welding to a 3" or 3-1/4" diameter tube. Ultimate axles provide a 13% weight savings over MW Superlight Hi-Torque axles and 39% weight savings over standard MW Hi-Torque axles. (Wheel studs are not included) Installation - Service instructions can be found on Service Bulletin #0087. Download the axle order form, Service Bulletin #0077, for guidance on required measurements.
