This is an optional 13T Hardened steel clutch bell for 1/8th scale buggies, and trucks from Fioroni. These clutch bells are precision cut and tempered to give you the best worry free performance. The larger the clutch bell, the more top end speed the vehicle will have, but will provide less bottom end acceleration. This would be good for smaller tracks with shorter straights where more bottom end acceleration is needed.
NOTE: This Clutch Bell uses 5x10mm bearings.
