I just bought a '96 LT4, and the dealership mounted these bad boyz up before I could stop them. Must have been a good deal though, because a new serpentine belt, and 2 F1's on the rears added $750 to the car.
Anyway, It takes a lot (Tons!) to get these to slip. I was testing ARS, and tried to dump hard on a wet road. They still would not let go. I shifted 2nd REAL hard, and got about 2 turns out of them. They look real sharp too!!
