This is the Team Integy 18-Tooth Lightweight Vented Steel Clutch Bell for the Traxxas Revo 2.5 and 3.3 trucks. The vented design allows for better cooling of the clutch assembly. A clutch bell with a greater number of teeth will increase the top-end speed of your truck. A clutch bell with a lower number of teeth will increase the acceleration of your truck.
