 Technical Notes & Replacement Parts

  • We do NOT recommend using these pistons with a stock GM Z06 427 crankshaft. The balance weight of the factory titanium connectings rod and hyperutectic pistons is extremely light and using this piston and steel connecting rod combination will require an expensive amount of heavy metal
