Damn. All aluminum body. All steel tooth rack. Second-last tooth removed for HS applications.

This may be my next piston.

Hmmm! This looks promising. Although... its common to strip a piston due to some sort of failure, so now if it won't break as easily, is there a chance that something more expensive could get damaged, like a gear set or motor?
