Thanks in advance for the help. Have my Gen 4 apart and while I wasn't planning on tearing it all apart - it might make sense "While I Was There" to change out to the Gen 5 pistons. If anyone has a set in great shape with hopefully low miles on them that they want to sell, let me know. Located in Phoenix BTW. And since I believe every post should have a pic ... here's what a little detonation does to a gen 4 piston :


Best personal regards,
