Thick or Thin wall axle??


New member
Thinking of ordering a new axle this winter for my kart as im told they wear out over time. Wonerding which axle would be of more benefit to me, thick or thin wall. Kart is a 07 ultramax inferno and currently has the axle that came on it which is the thick wall chromoly i believe.
Posted this in the phantom forum but haven't received a reply after 80+views........Is the standard Triton axle mild steel and what would the affects be of switching to a chromoly rear axle of the same wall thickness?
