    Piston cracked after installing supplied piston rings
  

*by Z***S on Reviewed in the United States on October 25, 2021*

I installed the piston rings on the piston and after doing so I was rotating the piston to check the rings and noticed a crack had formed along the wall of the piston. Since this is going into something that will be held at high rpm for long periods the crack renders the piston useless.
