omg, on a truck, to gain more traction off road, you turn your limited slip, or open diff to a straight axel by putting a locker in it or having a I think its called a spinddel job done on it at a four wheel shop, so the same amount of power is sent to both wheels even when turning, very useful when rock crawling, because street basics suck for offroading, but you can apply the locker to a regular street car for way better traction, I hope thats what you wanted because I read the begging real fast.
