REDS Racing have introduced an updated version of the Durabell clutch bell with a new special silver surface treatment which increases surface quality and wear resistance. 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 drivetrain with consistency and reliability. 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, Losi, Tekno, JQ, XRAY, Team Associated, HB Racing and Serpent.
