Can anyone tell me a good strong live axle I can buy I see some for 20 bucks and some for 80 bucks what is a good strong axle to buy for a heavy gokart and a heavy rider
A piece of 1" keyed steel shaft will do, depending on your application you may need to up a size, but the components will need to be sized accordingly. Also, Those parts might be rare or don't exsist, so you may need to machine your own.
it's not only the keyway,the ends should be machined as well.. so it might be easy (DIY) it might be cheap (friend) or it may be expensive and thus pointless (some shops)
