Without a doubt, the RLR Black-Magic clutch disc is the best disc available anywhere, made of the same material as a Top Fuel clutch disc. These discs have a superior coefficient of friction when compared to a 3- or 4-puck disc. With one of these discs, you will experience an increase in tranny life while at the same time, bettering your 60-foot times! What other performance products can say that?
Beware of imitations!
