yeah its the one inch with the weak spider gear diff

 

[freakboy]

i would weld that freaking thing up solid ahahah.... make a lincoln locker outa it ahaha.

 

[junior]

if i could i would. right where the split is i need a sproket hub.

If you go 4140 chromoly steel 1" will probably work, and you can use the same bearings, etc.

the way im lookin at it, im gonna put shorter tires and some suspension on it. i dont take it off road much (more of an incliment weather kart). and i cant find parts. the one inch is a direct swap from what i have now i can reuse everthing and be riding again sooner.

think im gonna get this

unless i can find a hardend one the same length or longer.

I'd just buy from a steel shop. A bar of 4140 chromoly 1 1/4" 50" long was under $50 AUD, but I suppose if you don't have a lathe and mill it's difficult to put the keyways and threads on the ends. FWIW I think that axle will most likely work, but you never know. That is a hell of a lot of power, but maybe the spinning of the tyres and wheelies will stop you putting too much stress on the axle.

yeah i know but the one incher is overkill for anything under at least 60 horse. regular cars use a one incher and they are putting down more power and moving more weight. they dont break.

actually wait... i got that wrong. 30mm mild steel, except for the stepdown 25mm ends. oops!

But remember in a car say a front wheel drive car it may have a 1" axle but how far away is the hub from the bearing assembly? 1" if that?

 

[modelengineer]

Yes, the only load on a car axle is torsional. Kart axles have bending loads on them.

ok so im gonna go with the 1 1/4. couple questions on that. were do i find wheel hubs and a solid axle?
