If you are tired of losing prop shafts and your expensive props then the CC Racing Heavy Duty Super Collet is the collet you are looking for. This is a new improved design that puts the crimping force of the insert at the end of the collet instead of inside the collet where your shaft can slip out. Once you have used one of these you will never buy any other collet. This is made out high quality Stainless Steel and is a heavy duty unit that uses standard 5/8 wrenches to tighten on the shaft.
This collet is for made to work with 1/4" cable. It fits Zenoah, Zenoah Clones, QD, Arrowshark, RCMK, CY, Sikk, and Venom gas engines.
We recomend to check fit on 4 bearing cases like Quickdraw, Arrowshark and RCMK to make sure there is no contact with bearing or seal! Some of these engines will require the collet to be shortened on the backside as to not rub.
