I just recieved my DGL. The cap to the additive that came with had came off during shipping. Does anyone know what the additive is exactly. I would like to install it this weekend and do not want to wait for high lifter to ship me some new stuff. I am gonna check the local axle shop and see if they know or if they have any. The stuff should be readily available if you are supposed to use it with every gear oil change. If anyone can help please let me know. Im dying to install this thing this weekend.
