What exactly causes a truck to crack? Is it due to landing drops with a smaller amount of metal on the truck? Or just from grinding certain things? I always love the way it looks but it’s never happened to me
For some who grind through like that, it is just the sheer wear of the truck, more than any heavy weight, hard landing or anything else.
That said, I do know some trucks break more weirdly than others (not including ti axles with all their issues), but gradually grinding through the axle, it weakens the material around it to the point where it just can't hold up anymore, sometimes bends so the hanger is still attached with the wheel hard pressed on the board, other times it just snaps off and goes flying.
