Diff lockers?

not from the factory, no lockers but you should be able to get the codes off you diff tags and see if its limited slip or something like that
Don't know what your plans are but if you are planning on getting a locker but don't rock crawl I would recommend truetracs i have them in the front and rear and there is no hesitation when one wheel slips just a little and with BLD it locks up the wheel in the air that has no traction and sends it to the wheel that does. It is the closest thing to a locker without all the trouble of one. I've had lockers and recommend the truetracs. Just my thoughts.
