Base, Open Differential Model:
Does not require an extra axle stub shafts, but the original axle stubs will have to be cut so the tips are flat. If you do not want to cut them, you can purchase both flat tip axle stubs for a direct bolt-on install.

Sport, VLSD Differential Model:
Extra Axle Stub Purchase Required. The VLSD model already comes with an original flat tip axle stub, so only 1 extra flat axle stub is required.
