Open Carrier

Drop-in lockers require the use of an open differential carrier. A standard open carrier uses spider gears to allow the axleshafts to rotate freely and at different speeds. Be sure to double-check that your carrier is in good shape (free of cracks) and it’s actually an open carrier. To the untrained eye some OE-style limited slips may appear to be open, but they are not and will not work with the Lock Right or Powertrax.
