REDS Racing announced the introduction of the new competition Durabell clutch bell. The new long wear clutch bell is made of high quality steel and the special coating treatment allows the teeth to last longer than any other standard clutch bell on the market, transferring power from the clutch to the center spur gear and the rest of the drive train with consistency and reliability. Its inner diameter is 26.6mm and it is necessary to use 5x10x4mm bearings size.
A special vented design also guarantees lower temperatures and more clean shoes engagement for a longer life of both bell and clutch shoes. Durabell is available in 13 and 14 teeth version only and it is suitable for Kyosho, Mugen, JQ, Xray, Associated, HB and Serpent. Durabell does not replace our standard 13 and 14 teeth clutch bells.
