Drag Racing With Clutch Type Sure-grip

The trouble is, there are no new clutch type. The auburn is a cone, and they admit it's not rebuildable (even though it is). That leaves the gear types, that most LOVE , but I have heard of problems. Then there is the dapco (Detroit automotive products co., known as the Detroit locker) VERY strong, but noisy, and has its quirks. Also, there are lockers that can be put in an open carrier. I haven't tried those, but I'm going to, in a nine inch, cause nine inch posi's are even worse that the 8 3/4 cone.
