Yea I thought of that. I was hoping someone might make a longer one or have another idea. I know a longer axle may require some extra support bearings.
I'm building a 2 seater 1000cc kart. I'm trying to find a solution for the axle. I need a 50mm axle but the longest one I can find is 1040mm, roughly 40 inches long. Any ideas on who makes a longer axle? Or other ideas on another solution?
