Other then a long slip. I don't get the whole square shaft thing. More expensive, doesn't balance, rattles,etc.. All you need is a stock shaft and 1 piece of the correct tube and you have a better shaft for cheaper.
You are not wrong. Honestly, this truck didn't need much travel so that wasn't really a factor. We didn't have a driveshaft for it at all and making our own was the route that the owner wanted to take. If we already had a driveshaft that could have been shortened or lengthened then I am sure we would have just done that.
Really cool truck build but Square driveshaft is not good in my opinion owners could have bought a custom Driveshaft for the price of all those U joints and shit that he bought
