Thought I would give some input on the EZ locker since I am running one on my Grabber street strip car. The posi part works great so far after one season of racing, not real noisy like a true locker, the one down fall I see in it is that there is a certain amount of play in unit before it actually engauges, meaning that it takes about 6 inches of travel before it locks up, so when you are at the line wanting to take off you had better have the rpm up and on the brakes or when you drop the hammer at the line there is a lag before take off, just something to get used too, and when car is on trailer the dang thing wont just sit there in park it want to roll back and forth cause it is not locked in. All in all after getting used to it I like it, but if my car was strictly drag it would have a full spool in it.
