Yes, the factory Viper part.
Kind of off topic but, one thing that has always concerned me was the clutch master fluid turned black fairly quickly almost like it had burnt. Clutch release was immediate and at top of pedal travel. Before the install, I questioned American Powertrain about measuring release and shimming and was told it was not needed with the hydraulic release set up. I always had a suspicion the release bearing was not fully disengaged and was spinning when it wasnt supposed to and overheating the fluid.
