These Drive shafts work perfectly. My friend was driving my car and hit a mailbox which unfortunately bent a shaft. Thankfully OEM Traxxas parts are interchangeable with these so you’ll have no issue fixing them if they break. Also these are soooo much cheaper than buying the Traxxas ones so these are very worth buying.
